in the markup.\nIn this article, I\u2019m going to take a look at the common features of our new layout systems, along with a couple of examples which serve to highlight the differences between them.\nTo see the grid layout examples you will need to enable grid in your browser. The easiest thing to do is to enable the experimental web platform features flag in Chrome. Details of current browser support can be found here. \nRelationship\nItems only become flex or grid items if they are a direct child of the element that has display:flex, display:grid or display:inline-grid applied. Those direct children then understand themselves in the context of the complete layout. This makes many things possible. It\u2019s the lack of relationship between elements that makes our existing layout methods difficult to use. If we float two columns, left and right, we have no way to tell the shorter column to extend to the height of the taller one. We have expended a lot of effort trying to figure out the best way to make full-height columns work, using techniques that were never really designed for page layout.\nAt a very simple level, the relationship between elements means that we can easily achieve full-height columns. In flexbox:\nSee the Pen Flexbox equal height columns by rachelandrew (@rachelandrew) on CodePen.\n\nAnd in grid layout (requires a CSS grid-supporting browser):\nSee the Pen Grid equal height columns by rachelandrew (@rachelandrew) on CodePen.\n\nAlignment\nFull-height columns rely on our flex and grid items understanding themselves as part of an overall layout. They also draw on a third new specification: the box alignment module. If vertical centring is a gift you\u2019d like to have under your tree this Christmas, then this is the box you\u2019ll want to unwrap first.\nThe box alignment module takes the alignment and space distribution properties from flexbox and applies them to other layout methods. That includes grid layout, but also other layout methods. Once implemented in browsers, this specification will give us true vertical centring of all the things.\nOur examples above achieved full-height columns because the default value of align-items is stretch. The value ensured our columns stretched to the height of the tallest. If we want to use our new vertical centring abilities on all items, we would set align-items:center on the container. To align one flex or grid item, apply the align-self property.\nThe examples below demonstrate these alignment properties in both grid layout and flexbox. The portrait image of Widget the cat is aligned with the default stretch. The other three images are aligned using different values of align-self.\nTake a look at an example in flexbox:\nSee the Pen Flexbox alignment by rachelandrew (@rachelandrew) on CodePen.\n\nAnd also in grid layout (requires a CSS grid-supporting browser):\nSee the Pen Grid alignment by rachelandrew (@rachelandrew) on CodePen.\n\nThe alignment properties used with CSS grid layout.\nFluid grids\nA cornerstone of responsive design is the concept of fluid grids.\n\n\u201c[\u2026]every aspect of the grid\u2014and the elements laid upon it\u2014can be expressed as a proportion relative to its container.\u201d\n\u2014Ethan Marcotte, \u201cFluid Grids\u201d\n\nThe method outlined by Marcotte is to divide the target width by the context, then use that value as a percentage value for the width property on our element.\nh1 {\n margin-left: 14.575%; /*\u00a0144px / 988px = 0.14575\u00a0*/\n width: 70.85%; /*\u00a0700px / 988px = 0.7085\u00a0*/\n}\nIn more recent years, we\u2019ve been able to use calc() to simplify this (at least, for those of us able to drop support for Internet Explorer 8). However, flexbox and grid layout make fluid grids simple.\nThe most basic of flexbox demos shows this fluidity in action. The justify-content property \u2013 another property defined in the box alignment module \u2013 can be used to create an equal amount of space between or around items. As the available width increases, more space is assigned in proportion.\nIn this demo, the list items are flex items due to display:flex being added to the ul. I have given them a maximum width of 250 pixels. Any remaining space is distributed equally between the items as the justify-content property has a value of space-between.\nSee the Pen Flexbox: justify-content by rachelandrew (@rachelandrew) on CodePen.\n\nFor true fluid grid-like behaviour, your new flexible friends are flex-grow and flex-shrink. These properties give us the ability to assign space in proportion.\nThe flexbox flex property is a shorthand for:\n\nflex-grow\nflex-shrink\nflex-basis\n\nThe flex-basis property sets the default width for an item. If flex-grow is set to 0, then the item will not grow larger than the flex-basis value; if flex-shrink is 0, the item will not shrink smaller than the flex-basis value.\n\nflex: 1 1 200px: a flexible box that can grow and shrink from a 200px basis.\nflex: 0 0 200px: a box that will be 200px and cannot grow or shrink.\nflex: 1 0 200px: a box that can grow bigger than 200px, but not shrink smaller.\n\nIn this example, I have a set of boxes that can all grow and shrink equally from a 100 pixel basis.\nSee the Pen Flexbox: flex-grow by rachelandrew (@rachelandrew) on CodePen.\n\nWhat I would like to happen is for the first element, containing a portrait image, to take up less width than the landscape images, thus keeping it more in proportion. I can do this by changing the flex-grow value. By giving all the items a value of 1, they all gain an equal amount of the available space after the 100 pixel basis has been worked out.\nIf I give them all a value of 3 and the first box a value of 1, the other boxes will be assigned three parts of the available space while box 1 is assigned only one part. You can see what happens in this demo:\nSee the Pen Flexbox: flex-grow by rachelandrew (@rachelandrew) on CodePen.\n\nOnce you understand flex-grow, you should easily be able to grasp how the new fraction unit (fr, defined in the CSS grid layout specification) works. Like flex-grow, this unit allows us to assign available space in proportion. In this case, we assign the space when defining our track sizes.\nIn this demo (which requires a CSS grid-supporting browser), I create a four-column grid using the fraction unit to define my track sizes. The first track is 1fr in width, and the others 2fr.\ngrid-template-columns: 1fr 2fr 2fr 2fr;\nSee the Pen Grid fraction units by rachelandrew (@rachelandrew) on CodePen.\n\nThe four-track grid.\nSeparation of concerns\nMy younger self petitioned my peers to stop using tables for layout and to move to CSS. One of the rallying cries of that movement was the concept of separating our source and content from how they were displayed. It was something of a failed promise given the tools we had available: the display leaked into the markup with the need for redundant elements to cope with browser bugs, or visual techniques that just could not be achieved without supporting markup.\nBrowsers have improved, but even now we can find ourselves compromising the ideal document structure so we can get the layout we want at various breakpoints. In some ways, the situation has returned to tables-for-layout days. Many of the current grid frameworks rely on describing our layout directly in the markup. We add divs for rows, and classes to describe the number of desired columns. We nest these constructions of divs inside one another.\nHere is a snippet from the Bootstrap grid examples \u2013 two columns with two nested columns:\n
\n
\n .col-md-8\n
\n
\n .col-md-6\n
\n
\n .col-md-6\n
\n
\n
\n
\n .col-md-4\n
\n
\nNot a million miles away from something I might have written in 1999.\n
\n \n \n .col-md-8\n \n \n | \n .col-md-6\n | \n \n .col-md-6\n | \n \n \n | \n \n .col-md-4\n | \n
\n
\nGrid and flexbox layouts do not need to be described in markup. The layout description happens entirely in the CSS, meaning that elements can be moved around from within the presentation layer.\nFlexbox gives us the ability to reverse the flow of elements, but also to set the order of elements with the order property. This is demonstrated here, where Widget the cat is in position 1 in the source, but I have used the order property to display him after the things that are currently unimpressive to him.\nSee the Pen Flexbox: order by rachelandrew (@rachelandrew) on CodePen.\n\nGrid layout takes this a step further. Where flexbox lets us set the order of items in a single dimension, grid layout gives us the ability to position things in two dimensions: both rows and columns. Defined in the CSS, this positioning can be changed at any breakpoint without needing additional markup. Compare the source order with the display order in this example (requires a CSS grid-supporting browser):\nSee the Pen Grid positioning in two dimensions by rachelandrew (@rachelandrew) on CodePen.\n\nLaying out our items in two dimensions using grid layout.\nAs these demos show, a straightforward way to decide if you should use grid layout or flexbox is whether you want to position items in one dimension or two. If two, you want grid layout.\nA note on accessibility and reordering\nThe issues arising from this powerful ability to change the way items are ordered visually from how they appear in the source have been the subject of much discussion. The current flexbox editor\u2019s draft states\n\n\u201cAuthors must use order only for visual, not logical, reordering of content. Style sheets that use order to perform logical reordering are non-conforming.\u201d\n\u2014CSS Flexible Box Layout Module Level 1, Editor\u2019s Draft (3 December 2015)\n\nThis is to ensure that non-visual user agents (a screen reader, for example) can rely on the document source order as being correct. Take care when reordering that you do so from the basis of a sound document that makes sense in terms of source order. Avoid using visual order to convey meaning.\nAutomatic content placement with rules\nHaving control over the order of items, or placing items on a predefined grid, is nice. However, we can often do that already with one method or another and we have frameworks and tools to help us. Tools such as Susy mean we can even get away from stuffing our markup full of grid classes. However, our new layout methods give us some interesting new possibilities.\nSomething that is useful to be able to do when dealing with content coming out of a CMS or being pulled from some other source, is to define a bunch of rules and then say, \u201cDisplay this content, using these rules.\u201d\nAs an example of this, I will leave you with a Christmas poem displayed in a document alongside Widget the cat and some of the decorations that are bringing him no Christmas cheer whatsoever.\nThe poem is displayed first in the source as a set of paragraphs. I\u2019ve added a class identifying each of the four paragraphs but they are displayed in the source as one text. Below that are all my images, some landscape and some portrait; I\u2019ve added a class of landscape to the landscape ones.\nThe mobile-first grid is a single column and I use line-based placement to explicitly position my poem paragraphs. The grid layout auto-placement rules then take over and place the images into the empty cells left in the grid.\nAt wider screen widths, I declare a four-track grid, and position my poem around the grid, keeping it in a readable order.\nI also add rules to my landscape class, stating that these items should span two tracks. Once again the grid layout auto-placement rules position the rest of my images without my needing to position them. You will see that grid layout takes items out of source order to fill gaps in the grid. It does this because I have set the property grid-auto-flow to dense. The default is sparse meaning that grid will not attempt this backfilling behaviour.\nTake a look and play around with the full demo (requires a CSS grid layout-supporting browser):\nSee the Pen Grid auto-flow with rules by rachelandrew (@rachelandrew) on CodePen.\n\nThe final automatic placement example.\nMy wish for 2016\nI really hope that in 2016, we will see CSS grid layout finally emerge from behind browser flags, so that we can start to use these features in production \u2014 that we can start to move away from using the wrong tools for the job.\nHowever, I also hope that we\u2019ll see developers fully embracing these tools as the new system that they are. I want to see people exploring the possibilities they give us, rather than trying to get them to behave like the grid systems of 2015. As you discover these new modules, treat them as the new paradigm that they are, get creative with them. And, as you find the edges of possibility with them, take that feedback to the CSS Working Group. Help improve the layout systems that will shape the look of the future web.\nSome further reading\n\nI maintain a site of grid layout examples and resources at Grid by Example.\nThe three CSS specifications I\u2019ve discussed can be found as editor\u2019s drafts: CSS grid, flexbox, box alignment.\nI wrote about the last three years of my interest in CSS grid layout, which gives something of a history of the specification.\nMore examples of box alignment and grid layout.\nMy presentation at Fronteers earlier this year, in which I explain more about these concepts.", "year": "2015", "author": "Rachel Andrew", "author_slug": "rachelandrew", "published": "2015-12-15T00:00:00+00:00", "url": "https://24ways.org/2015/grid-flexbox-box-alignment-our-new-system-for-layout/", "topic": "code"}
{"rowid": 71, "title": "Upping Your Web Security Game", "contents": "When I started working in web security fifteen years ago, web development looked very different. The few non-static web applications were built using a waterfall process and shipped quarterly at best, making it possible to add security audits before every release; applications were deployed exclusively on in-house servers, allowing Info Sec to inspect their configuration and setup; and the few third-party components used came from a small set of well-known and trusted providers. And yet, even with these favourable conditions, security teams were quickly overwhelmed and called for developers to build security in.\nIf the web security game was hard to win before, it\u2019s doomed to fail now. In today\u2019s web development, every other page is an application, accepting inputs and private data from users; software is built continuously, designed to eliminate manual gates, including security gates; infrastructure is code, with servers spawned with little effort and even less security scrutiny; and most of the code in a typical application is third-party code, pulled in through open source repositories with rarely a glance at who provided them.\nSecurity teams, when they exist at all, cannot solve this problem. They are vastly outnumbered by developers, and cannot keep up with the application\u2019s pace of change. For us to have a shot at making the web secure, we must bring security into the core. We need to give it no less attention than that we give browser compatibility, mobile design or web page load times. More broadly, we should see security as an aspect of quality, expecting both ourselves and our peers to address it, and taking pride when we do it well.\nWhere To Start?\nEmbracing security isn\u2019t something you do overnight.\nA good place to start is by reviewing things you\u2019re already doing \u2013 and trying to make them more secure. Here are three concrete steps you can take to get going.\nHTTPS\nThreats begin when your system interacts with the outside world, which often means HTTP. As is, HTTP is painfully insecure, allowing attackers to easily steal and manipulate data going to or from the server. HTTPS adds a layer of crypto that ensures the parties know who they\u2019re talking to, and that the information exchanged can be neither modified nor sniffed.\nHTTPS is relevant to any site. If your non-HTTPS site holds opinions, reading it may get your users in trouble with employers or governments. If your users believe what you say, attackers can modify your non-HTTPS to take advantage of and abuse that trust. If you want to use new browser technologies like HTTP2 and service workers, your site will need to be HTTPS. And if you want to be discovered on the web, using HTTPS can help your Google ranking. For more details on why I think you should make the switch to HTTPS, check out this post, these slides and this video.\nUsing HTTPS is becoming easier and cheaper. Here are a few free tools that can help:\n\nGet free and easy HTTPS delivery from Cloudflare (be sure to use \u201cFull SSL\u201d!)\nGet a free and automation-friendly certificate from Let\u2019s Encrypt (now in open beta).\nTest how well your HTTPS is set up using SSLTest.\n\nOther vendors and platforms are rapidly simplifying and reducing the cost of their HTTPS offering, as demand and importance grows.\nTwo-Factor Authentication\nThe most sensitive data is usually stored behind a login, and the authentication process is the primary gate in front of this data. Making this process secure has many aspects, including using HTTPS when accepting credentials, having a strong password policy, never storing the password, and more.\nAll of these are important, but the best single step to boost your authentication security is to introduce two-factor authentication (2FA). Adding 2FA usually means prompting users for an additional one-time code when logging in, which they get via SMS or a mobile app (e.g. Google Authenticator). This code is short-lived and is extremely hard for a remote attacker to guess, thus vastly reducing the risk a leaked or easily guessed password presents.\nThe typical algorithm for 2FA is based on an IETF standard called the time-based one-time password (TOTP) algorithm, and it isn\u2019t that hard to implement. Joel Franusic wrote a great post on implementing 2FA; modules like speakeasy make it even easier; and you can swap SMS with Google Authenticator or your own app if you prefer. If you don\u2019t want to build 2FA support yourself, you can purchase two/multi-factor authentication services from vendors such as DuoSecurity, Auth0, Clef, Hypr and others.\nIf implementing 2FA still feels like too much work, you can also choose to offload your entire authentication process to an OAuth-based federated login. Many companies offer this today, including Facebook, Google, Twitter, GitHub and others. These bigger players tend to do authentication well and support 2FA, but you should consider what data you\u2019re sharing with them in the process.\nTracking Known Vulnerabilities\nMost of the code in a modern application was actually written by third parties, and pulled into your app as frameworks, modules and libraries. While using these components makes us much more productive, along with their functionality we also adopt their security flaws. To make things worse, some of these flaws are well-known vulnerabilities, making it easy for hackers to take advantage of them in an attack.\nThis is a real problem and happens on pretty much every platform. Do you develop in Java? In 2014, over 6% of Java modules downloaded from Maven had a known severe security issue, the typical Java applications containing 24 flaws. Are you coding in Node.js? Roughly 14% of npm packages carry a known vulnerability, and over 60% of dev shops find vulnerabilities in their code. 30% of Docker Hub containers include a high priority known security hole, and 60% of the top 100,000 websites use client-side libraries with known security gaps.\nTo find known security issues, take stock of your dependencies and match them against language-specific lists such as Snyk\u2019s vulnerability DB for Node.js, rubysec for Ruby, victims-db for Python and OWASP\u2019s Dependency Check for Java. Once found, you can fix most issues by upgrading the component in question, though that may be tricky for indirect dependencies. \nThis process is still way too painful, which means most teams don\u2019t do it. The Snyk team and I are hoping to change that by making it as easy as possible to find, fix and monitor known vulnerabilities in your dependencies. Snyk\u2019s wizard will help you find and fix these issues through guided upgrades and patches, and adding Snyk\u2019s test to your continuous integration and deployment (CI/CD) will help you stay secure as your code evolves.\nNote that newly disclosed vulnerabilities usually impact old code \u2013 the one you\u2019re running in production. This means you have to stay alert when new vulnerabilities are disclosed, so you can fix them before attackers can exploit them. You can do so by subscribing to vulnerability lists like US-CERT, OSVDB and NVD. Snyk\u2019s monitor will proactively let you know about new disclosures relevant to your code, but only for Node.js for now \u2013 you can register to get updated when we expand.\nSecuring Yourself\nIn addition to making your application secure, you should make the contributors to that application secure \u2013 including you. Earlier this year we\u2019ve seen attackers target mobile app developers with a malicious Xcode. The real target, however, wasn\u2019t these developers, but rather the users of the apps they create. That you create. Securing your own work environment is a key part of keeping your apps secure, and your users from being compromised.\nThere\u2019s no single step that will make you fully secure, but here are a few steps that can make a big impact:\n\nUse 2FA on all the services related to the application, notably source control (e.g. GitHub), cloud platform (e.g. AWS), CI/CD, CDN, DNS provider and domain registrar. If an attacker compromises any one of those, they could modify or replace your entire application. I\u2019d recommend using 2FA on all your personal services too.\nUse a password manager (e.g. 1Password, LastPass) to ensure you have a separate and complex password for each service. Some of these services will get hacked, and passwords will leak. When that happens, don\u2019t let the attackers access your other systems too.\nSecure your workstation. Be careful what you download, lock your screen when you walk away, change default passwords on services you install, run antivirus software, etc. Malware on your machine can translate to malware in your applications.\nBe very wary of phishing. Smart attackers use \u2018spear phishing\u2019 techniques to gain access to specific systems, and can trick even security savvy users. There are even phishing scams targeting users with 2FA. Be alert to phishy emails.\nDon\u2019t install things through curl
| sudo bash, especially if the URL is on GitHub, meaning someone else controls it. Don\u2019t do it on your machines, and definitely don\u2019t do it in your CI/CD systems. Seriously.\n\nStaying secure should be important to you personally, but it\u2019s doubly important when you have privileged access to an application. Such access makes you a way to reach many more users, and therefore a more compelling target for bad actors.\nA Culture of Security\nUsing HTTPS, enabling two-factor authentication and fixing known vulnerabilities are significant steps in building security at your core. As you implement them, remember that these are just a few steps in a longer journey.\nThe end goal is to embrace security as an aspect of quality, and accept we all share the responsibility of keeping ourselves \u2013 and our users \u2013 safe.", "year": "2015", "author": "Guy Podjarny", "author_slug": "guypodjarny", "published": "2015-12-11T00:00:00+00:00", "url": "https://24ways.org/2015/upping-your-web-security-game/", "topic": "code"}
{"rowid": 72, "title": "Designing with Contrast", "contents": "When an appetite for aesthetics over usability becomes the bellwether of user interface design, it\u2019s time to reconsider who we\u2019re designing for.\nOver the last few years, we have questioned the signifiers that gave obvious meaning to the function of interface elements. Strong textures, deep shadows, gradients \u2014 imitations of physical objects \u2014 were discarded. And many, rightfully so. Our audiences are now more comfortable with an experience that feels native to the technology, so we should respond in kind.\nYet not all of the changes have benefitted users. Our efforts to simplify brought with them a trend of ultra-minimalism where aesthetics have taken priority over legibility, accessibility and discoverability. The trend shows no sign of losing popularity \u2014 and it is harming our experience of digital content.\n\nA thin veneer\nWe are in a race to create the most subdued, understated interface. Visual contrast is out. In its place: the thinnest weights of a typeface and white text on bright color backgrounds. Headlines, text, borders, backgrounds, icons, form controls and inputs: all grey.\nWhile we can look back over the last decade and see minimalist trends emerging on the web, I think we can place a fair share of the responsibility for the recent shift in priorities on Apple. The release of iOS 7 ushered in a radical change to its user interface. It paired mobile interaction design to the simplicity and eloquence of Apple\u2019s marketing and product design. It was a catalyst. We took what we saw, copied and consumed the aesthetics like pick-and-mix.\nNew technology compounds this trend. Computer monitors and mobile devices are available with screens of unprecedented resolutions. Ultra-light type and subtle hues, difficult to view on older screens, are more legible on these devices. It would be disingenuous to say that designers have always worked on machines representative of their audience\u2019s circumstances, but the gap has never been as large as it is now. We are running the risk of designing VIP lounges where the cost of entry is a Mac with a Retina display.\nMinimalist expectations\nLike progressive enhancement in an age of JavaScript, many good and sensible accessibility practices are being overlooked or ignored. We\u2019re driving unilateral design decisions that threaten accessibility. We\u2019ve approached every problem with the same solution, grasping on to the integrity of beauty, focusing on expression over users\u2019 needs and content. \nSomeone once suggested to me that a client\u2019s website should include two states. The first state would be the ideal experience, with low color contrast, light font weights and no differentiation between links and text. It would be the default. The second state would be presented in whatever way was necessary to meet accessibility standards. Users would have to opt out of the default state via a toggle if it wasn\u2019t meeting their needs. A sort of first-class, upper deck cabin equivalent of graceful degradation. That this would divide the user base was irrelevant, as the aesthetics of the brand were absolute. \nIt may seem like an unusual anecdote, but it isn\u2019t uncommon to see this thinking in our industry. Again and again, we place the burden of responsibility to participate in a usable experience on others. We view accessibility and good design as mutually exclusive. Taking for granted what users will tolerate is usually the forte of monopolistic services, but increasingly we apply the same arrogance to our new products and services.\n\nImitation without representation\nAll of us are influenced in one way or another by one another\u2019s work. We are consciously and unconsciously affected by the visual and audible activity around us. This is important and unavoidable. We do not produce work in a vacuum. We respond to technology and culture. We channel language and geography. We absorb the sights and sounds of film, television, news. To mimic and copy is part and parcel of creating something an audience of many can comprehend and respond to. Our clients often look first to their competitors\u2019 products to understand their success.\nHowever, problems arise when we focus on style without context; form without function; mimicry as method. Copied and reused without any of the ethos of the original, stripped of deliberate and informed decision-making, the so-called look and feel becomes nothing more than paint on an empty facade.\nThe typographic and color choices so in vogue today with our popular digital products and services have little in common with the brands they are meant to represent.\n\nFor want of good design, the message was lost\nThe question to ask is: does the interface truly reflect the product? Is it an accurate characterization of the brand and organizational values? Does the delivery of the content match the tone of voice?\nThe answer is: probably not. Because every organization, every app or service, is unique. Each with its own personality, its own values and wonderful quirks. Design is communication. We should do everything in our role as professionals to use design to give voice to the message. Our job is to clearly communicate the benefits of a service and unreservedly allow access to information and content. To do otherwise, by obscuring with fashionable styles and elusive information architecture, does a great disservice to the people who chose to engage with and trust our products.\nWe can achieve hierarchy and visual rhythm without resorting to extreme reduction. We can craft a beautiful experience with fine detail and curiosity while meeting fundamental standards of accessibility (and strive to meet many more).\nStandards of excellence\nIt isn\u2019t always comfortable to step back and objectively question our design choices. We get lost in the flow of our work, using patterns and preferences we\u2019ve tried and tested before. That our decisions often seem like second nature is a gift of experience, but sometimes it prevents us from finding our blind spots.\nI was first caught out by my own biases a few years ago, when designing an interface for the Bank of England. After deciding on the colors for the typography and interactive elements, I learned that the site had to meet AAA accessibility standards. My choices quickly fell apart. It was eye-opening. I had to start again with restrictions and use size, weight and placement instead to construct the visual hierarchy.\nEven now, I make mistakes. On a recent project, I used large photographs on an organization\u2019s website to promote their products. Knowing that our team had control over the art direction, I felt confident that we could compose the photographs to work with text overlays. Despite our best effort, the cropped images weren\u2019t always consistent, undermining the text\u2019s legibility. If I had the chance to do it again, I would separate the text and image.\nSo, what practical things can we consider to give our users the experience they deserve?\nPut guidelines in place\n\nThink about your brand values. Write down keywords and use them as a framework when choosing a typeface. Explore colors that convey the organization\u2019s personality and emotional appeal.\nDefine a color palette that is web-ready and meets minimum accessibility standards. Note which colors are suitable for use with text. Only very dark hues of grey are consistently legible so keep them for non-essential text (for example, as placeholders in form inputs).\nFind which background colors you can safely use with white text, and consider integrating contrast checks into your workflow.\nUse roman and medium weights for body copy. Reserve lighter weights of a typeface for very large text. Thin fonts are usually the first to break down because of aliasing differences across platforms and screens.\nCheck that the size, leading and length of your type is always legible and readable. Define lower and upper limits. Small text is best left for captions and words in uppercase.\nAvoid overlaying text on images unless it\u2019s guaranteed to be legible. If it\u2019s necessary to optimize space in the layout, give the text a container. Scrims aren\u2019t always reliable: the text will inevitably overlap a part of the photograph without a contrasting ground.\n\nTest your work\n\nReview legibility and contrast on different devices. It\u2019s just as important as testing the layout of a responsive website. If you have a local device lab, pay it a visit.\nFind a computer monitor near a window when the sun is shining. Step outside the studio and try to read your content on a mobile device with different brightness levels. \nAsk your friends and family what they use at home and at work. It\u2019s one way of making sure your feedback isn\u2019t always coming from a closed loop.\n\nPush your limits\n\nYou define what the user sees. If you\u2019ve inherited brand guidelines, question them. If you don\u2019t agree with the choices, make the case for why they should change.\nExperiment with size, weight and color to find contrast. Objects with low contrast appear similar to one another and undermine the visual hierarchy. Weak relationships between figure and ground diminish visual interest. A balanced level of contrast removes ambiguity and creates focal points. It captures and holds our attention.\nIf you\u2019re lost for inspiration, look to graphic design in print. We have a wealth of history, full of examples that excel in using contrast to establish visual hierarchy.\nEmbrace limitations. Use boundaries as an opportunity to explore possibilities.\n\nMore than just a facade\nDesigning with standards encourages legibility and helps to define a strong visual hierarchy. Design without exclusion (through neither negligence or intent) gets around discussions of demographics, speaks to a larger audience and makes good business sense. Following the latest trends not only weakens usability but also hinders a cohesive and distinctive brand.\nUsers will make means when they need to, by increasing browser font sizes or enabling system features for accessibility. But we can do our part to take as much of that burden off of the user and ask less of those who need it most.\nIn architecture, it isn\u2019t buildings that mimic what is fashionable that stand the test of time. Nor do we admire buildings that tack on separate, poorly constructed extensions to meet a bare minimum of safety regulations. We admire architecture that offers well-considered, remarkable, usable spaces with universal access.\nPerhaps we can take inspiration from these spaces. Let\u2019s give our buildings a bold voice and make sure the doors are open to everyone.", "year": "2015", "author": "Mark Mitchell", "author_slug": "markmitchell", "published": "2015-12-13T00:00:00+00:00", "url": "https://24ways.org/2015/designing-with-contrast/", "topic": "design"}
{"rowid": 60, "title": "What\u2019s Ahead for Your Data in 2016?", "contents": "Who owns your data? Who decides what can you do with it? Where can you store it? What guarantee do you have over your data\u2019s privacy? Where can you publish your work? Can you adapt software to accommodate your disability? Is your tiny agency subject to corporate regulation? Does another country have rights over your intellectual property?\nIf you aren\u2019t the kind of person who is interested in international politics, I hate to break it to you: in 2016 the legal foundations which underpin our work on the web are being revisited in not one but three major international political agreements, and every single one of those questions is up for grabs. These agreements \u2013 the draft EU Data Protection Regulation (EUDPR), the Trans-Pacific Partnership (TPP), and the draft Transatlantic Trade and Investment Partnership (TTIP) \u2013 stand poised to have a major impact on your data, your workflows, and your digital rights. While some proposed changes could protect the open web for the future, other provisions would set the internet back several decades.\nIn this article we will review the issues you need to be aware of as a digital professional. While each of these agreements covers dozens of topics ranging from climate change to food safety, we will focus solely on the aspects which pertain to the work we do on the web.\nThe Trans-Pacific Partnership\nThe Trans-Pacific Partnership (TPP) is a free trade agreement between the US, Japan, Malaysia, Vietnam, Singapore, Brunei, Australia, New Zealand, Canada, Mexico, Chile and Peru \u2013 a bloc comprising 40% of the world\u2019s economy. The agreement is expected to be signed by all parties, and thereby to come into effect, in 2016. This agreement is ostensibly about the bloc and its members working together for their common interests. However, the latest draft text of the TPP, which was formulated entirely in secret, has only been made publicly available on a Medium blog published by the U.S. Trade Representative which features a patriotic banner at the top proclaiming \u201cTPP: Made in America.\u201d The message sent about who holds the balance of power in this agreement, and whose interests it will benefit, is clear.\nBy far the most controversial area of the TPP has centred around the provisions on intellectual property. These include copyright terms of up to 120 years, mandatory takedowns of allegedly infringing content in response to just one complaint regardless of that complaint\u2019s validity, heavy and disproportionate penalties for alleged violations, and \u2013 most frightening of all \u2013 government seizures of equipment allegedly used for copyright violations. All of these provisions have been raised without regard for the fact that a trade agreement is not the appropriate venue to negotiate intellectual property law.\nOther draft TPP provisions would restrict the digital rights of people with disabilities by banning the workarounds they use every day. These include no exemptions for the adaptations of copywritten works for use in accessible technology (such as text-to-speech in ebook readers), a ban on circumventing DRM or digital locks in order to convert a file to an accessible format, and requiring the takedown of adapted works, such as a video with added subtitles, even if that adaptation would normally have fallen under the definition of fair use.\nThe e-commerce provisions would prohibit data localisation, the practice of requiring data to be physically stored on servers within a country\u2019s borders. Data localisation is growing in popularity following the Snowden revelations, and some of your own personal data may have been recently \u201clocalised\u201d in response to the Safe Harbor verdict. Prohibiting data localisation through the TPP would address the symptom but not the cause.\nThe Electronic Frontier Foundation has published an excellent summary of the digital rights issues raised by the agreement along with suggested actions American readers can take to speak out.\nTransatlantic Trade and Investment Partnership\nTTIP stands for the Transatlantic Trade and Investment Partnership, a draft free trade agreement between the United States and the EU. The plan has been hugely controversial and divisive, and the internet and digital provisions of the draft form just a small part of that contention.\nThe most striking digital provision of TTIP is an attempt to circumvent and override European data protection law. As EDRI, a European digital rights organisation, noted:\n\n\u201cthe US proposal would authorise the transfer of EU citizens\u2019 personal data to any country, trumping the EU data protection framework, which ensures that this data can only be transferred in clearly defined circumstances. For years, the US has been trying to bypass the default requirement for storage of personal data in the EU. It is therefore not surprising to see such a proposal being {introduced} in the context of the trade negotiations.\u201d\n\nThis draft provision was written before the Safe Harbor data protection agreement between the EU and US was invalidated by the Court of Justice of the European Union. In other words, there is no longer any protective agreement in place, and our data is as vulnerable as this political situation. However, data protection is a matter of its own law, the acting Data Protection Directive and the draft EU Data Protection Reform. A trade agreement, be it the TTIP or the TPP, is not the appropriate place to revamp a law on data protection.\nOther digital law issues raised by TTIP include the possibility of renegotiating standards on encryption (which in practice means lowering them) and renegotiating intellectual property rights such as copyright. The spectre of net neutrality has even put in an appearance, with an attempt to introduce rules on access to the internet itself being introduced as provisions.\nTTIP is still under discussion, and this month the EU trade representative said that \u201cwe agreed to further intensify our work during 2016 to help negotiations move forward rapidly.\u201d This has been cleverly worded: this means the agreement has little chance of being passed or coming into effect in 2016, which buys civil society more precious time to speak out.\nThe EU Data Protection Regulation\nOn 15 December 2015 the European Commission announced their agreement on the text of the draft General Data Protection Regulation. This law will replace its predecessor, the EU Data Protection Regulation of 1995, which has done a remarkable job of protecting data privacy across the continent throughout two decades of constant internet evolution.\nThe goal of the reform process has been to return power over data, and its uses, to citizens. Users will have more control over what data is captured about them, how it is used, how it is retained, and how it can be deleted. Businesses and digital professionals, in turn, will have to restructure their relationships with client and customer data. Compliance obligations will increase, and difficult choices will have to be made. However, this time should be seen as an opportunity to rethink our relationship with data. After Snowden, Schrems, and Safe Harbor, it is clear that we cannot go back to the way things were before. In an era of where every one of our heartbeats is recorded on a wearable device and uploaded to a surveilled data centre in another country, the need for reform has never been more acute.\nWhile texts of the draft GDPR are available, there is not enough mulled wine in the world that will help you get through them. Instead, the law firm Fieldfisher Waterhouse has produced this helpful infographic which will give you a good idea of the changes we can expect to see (view full size):\n\nThe most surprising outcome announced on 15 December was the new regulation\u2019s teeth. Under the new law, companies that fail to heed the updated data protection rules will face fines of up to 4% of their global turnover. Additionally, the law expands the liability for data protection to both the controller (the company hosting the data) and the data processor (the company using the data). The new law will also introduce a one-stop shop for resolving concerns over data misuse. Companies will no longer be able to headquarter their European operations in countries which are perceived to have relatively light-touch data protection enforcement (that means you, Ireland) as a means of automatically rejecting any complaints filed by citizens outside that country.\nFor digital professionals, the most immediate concern is analytics. In fact, I am going to make a prediction: in 2016 we will begin to see the same misguided war on analytics that we saw on cookies. By increasing the legal liabilities for both data processors and controllers \u2013 in other words, the company providing the analytics as well as the site administrator studying them \u2013 the new regulation risks creating disproportionate burdens as well as the same \u201cguilt by association\u201d risks we saw in 2012. There have already been statements made by some within the privacy community that analytics are tracking, and tracking is surveillance, therefore analytics are evil. Yet \u201cjust don\u2019t use analytics,\u201d as was suggested by one advocate, is simply not an option. European regulators should consult with the web community to gain a clear understanding of why analytics are vital to everyday site administrators, and must find a happy medium that protects users\u2019 data without criminalising every website by default. No one wants a repeat of the crisis of consent, as well as the scaremongering, caused by the cookie law.\nAssuming the text is adopted in 2016, the new EU Data Protection Regulation would not come into effect until 2018. We have a considerable challenge ahead, but we also have plenty of time to get it right.", "year": "2015", "author": "Heather Burns", "author_slug": "heatherburns", "published": "2015-12-21T00:00:00+00:00", "url": "https://24ways.org/2015/whats-ahead-for-your-data-in-2016/", "topic": "business"}
{"rowid": 70, "title": "Bringing Your Code to the Streets", "contents": "\u2014 or How to Be a Street VJ\nOur amazing world of web code is escaping out of the browser at an alarming rate and appearing in every aspect of the environment around us. Over the past few years we\u2019ve already seen JavaScript used server-side, hardware coded with JavaScript, a rise of native style and desktop apps created with HTML, CSS and JavaScript, and even virtual reality (VR) is getting its fair share of front-end goodness.\nYou can go ahead and play with JavaScript-powered hardware such as the Tessel or the Espruino to name a couple. Just check out the Tessel project page to see JavaScript in the world of coffee roasting or sleep tracking your pet. With the rise of the internet of things, JavaScript can be seen collecting information on flooding among other things. And if that\u2019s not enough \u2018outside the browser\u2019 implementations, Node.js servers can even be found in aircraft!\nI previously mentioned VR and with three.js\u2019s extra StereoEffect.js module it\u2019s relatively simple to get browser 3D goodness to be Google Cardboard-ready, and thus set the stage for all things JavaScript and VR. It\u2019s been pretty popular in the art world too, with interactive works such as Seb Lee-Delisle\u2019s Lunar Trails installation, featuring the old arcade game Lunar Lander, which you can now play in your browser while others watch (it is the web after all). The Science Museum in London held Chrome Web Lab, an interactive exhibition featuring five experiments, showcasing the magic of the web. And it\u2019s not even the connectivity of the web that\u2019s being showcased; we can even take things offline and use web code for amazing things, such as fighting Ebola.\nOne thing is for sure, JavaScript is awesome. Hell, if you believe those telly programs (as we all do), JavaScript can even take down the stock market, purely through the witchcraft of canvas! Go JavaScript!\nNow it\u2019s our turn\nSo I wanted to create a little project influenced by this theme, and as it\u2019s Christmas, take it to the streets for a little bit of party fun! Something that could take code anywhere. Here\u2019s how I made a portable visual projection pack, a piece of video mixing software and created some web-coded street art.\nStep one: The equipment\nYou will need:\n\nOne laptop: with HDMI output and a modern browser installed, such as Google Chrome.\nOne battery-powered mini projector: I\u2019ve used a Texas Instruments DLP; for its 120 lumens it was the best cost-to-lumens ratio I could find.\nOne MIDI controller (optional): mine is an ICON iDJ as it suits mixing visuals. However, there is more affordable hardware on the market such as an Akai LPD8 or a Korg nanoPAD2. As you\u2019ll see in the article, this is optional as it can be emulated within the software.\nA case to carry it all around in.\n\n\nStep two: The software\nThe projected visuals, I imagined, could be anything you can create within a browser, whether that be simple HTML and CSS, images, videos, SVG or canvas. The only requirement I have is that they move or change with sound and that I can mix any one visual into another.\nYou may remember a couple of years ago I created a demo on this very site, allowing audio-triggered visuals from the ambient sounds your device mic was picking up. That was a great starting point \u2013 I used that exact method to pick up the audio and thus the first requirement was complete. If you want to see some more examples of visuals I\u2019ve put together for this, there\u2019s a showcase on CodePen.\nThe second requirement took a little more thought. I needed two screens, which could at any point show any of the visuals I had coded, but could be mixed from one into the other and back again. So let\u2019s start with two divs, both absolutely positioned so they\u2019re on top of each other, but at the start the second screen\u2019s opacity is set to zero.\nNow all we need is a slider, which when moved from one side to the other slowly sets the second screen\u2019s opacity to 1, thereby fading it in.\nSee the Pen Mixing Screens (Software Version) by Rumyra (@Rumyra) on CodePen.\nMixing Screens (CodePen)\n\nAs you saw above, I have a MIDI controller and although the software method works great, I\u2019d quite like to make use of this nifty piece of kit. That\u2019s easily done with the Web MIDI API. All I need to do is call it, and when I move one of the sliders on the controller (I\u2019ve allocated the big cross fader in the middle for this), pick up on the change of value and use that to control the opacity instead.\nvar midi, data;\n// start talking to MIDI controller\nif (navigator.requestMIDIAccess) {\n navigator.requestMIDIAccess({\n sysex: false\n }).then(onMIDISuccess, onMIDIFailure);\n} else {\n alert(\u201cNo MIDI support in your browser.\u201d);\n}\n\n// on success\nfunction onMIDISuccess(midiData) {\n // this is all our MIDI data\n midi = midiData;\n\n var allInputs = midi.allInputs.values();\n // loop over all available inputs and listen for any MIDI input\n for (var input = allInputs.next(); input && !input.done; input = allInputs.next()) {\n // when a MIDI value is received call the onMIDIMessage function\n input.value.onmidimessage = onMIDIMessage;\n }\n}\n\nfunction onMIDIMessage(message) {\n // data comes in the form [command/channel, note, velocity]\n data = message.data;\n\n // Opacity change for screen. The cross fader values are [176, 8, {0-127}]\n if ( (data[0] === 176) && (data[1] === 8) ) {\n // this value will change as the fader is moved\n var opacity = data[2]/127;\n screenTwo.style.opacity = opacity;\n }\n}\n\nThe final code was slightly more complicated than this, as I decided to switch the two screens based on the frequencies of the sound that was playing, and use the cross fader to depict the frequency threshold value. This meant they flickered in and out of each other, rather than just faded. There\u2019s a very rough-and-ready first version of the software on GitHub.\nPhew, Great! Now we need to get all this to the streets!\nStep three: Portable kit\nDid you notice how I mentioned a case to carry it all around in? I wanted the case to be morphable, so I could use the equipment from it too, a sort of bag-to-usherette-tray-type affair. Well, I had an unused laptop bag\u2026\n\nI strengthened it with some MDF, so when I opened the bag it would hold like a tray where the laptop and MIDI controller would sit. The projector was Velcroed to the external pocket of the bag, so when it was a tray it would project from underneath. I added two durable straps, one for my shoulders and one round my waist, both attached to the bag itself. There was a lot of cutting and trimming. As it was a laptop bag it was pretty thick to start and sewing was tricky. However, I only broke one sewing machine needle; I\u2019ve been known to break more working with leather, so I figured I was doing well. By the way, you can actually buy usherette trays, but I just couldn\u2019t resist hacking my own :)\nStep four: Take to the streets\nFirst, make sure everything is charged \u2013 everything \u2013 a lot! The laptop has to power both the MIDI controller and the projector, and although I have a mobile phone battery booster pack, that\u2019ll only charge the projector should it run out. I estimated I could get a good hour of visual artistry before I needed to worry, though.\nI had a couple of ideas about time of day and location. Here in the UK at this time of year, it gets dark around half past four, so I could easily head out in a city around 5pm and it would be dark enough for the projections to be seen pretty well. I chose Bristol, around the waterfront, as there were some interesting locations to try it out in. The best was Millennium Square: busy but not crowded and plenty of surfaces to try projecting on to.\nMy first time out with the portable audio/visual pack (PAVP as it will now be named) was brilliant. I played music and projected visuals, like a one-woman band of A/V!\n\n\nYou might be thinking what the point of this was, besides, of course, it being a bit of fun. Well, this project got me to look at canvas and SVG more closely. The Web MIDI API was really interesting; MIDI as a data format has some great practical uses. I think without our side projects we may not have all these wonderful uses for our everyday code. Not only do they remind us coding can, and should, be fun, they also help us learn and grow as makers.\nMy favourite part? When I was projecting into a water feature in Millennium Square. For those who are familiar, you\u2019ll know it\u2019s like a wall of water so it produced a superb effect. I drew quite a crowd and a kid came to stand next to me and all I could hear him say with enthusiasm was, \u2018Oh wow! That\u2019s so cool!\u2019\nYes\u2026 yes, kid, it was cool. Making things with code is cool.\nMassive thanks to the lovely Drew McLellan for his incredibly well-directed photography, and also Simon Johnson who took a great hand in perfecting the kit while it was attached.", "year": "2015", "author": "Ruth John", "author_slug": "ruthjohn", "published": "2015-12-06T00:00:00+00:00", "url": "https://24ways.org/2015/bringing-your-code-to-the-streets/", "topic": "code"}
