There has been a lot of industry discussion of late about designers and developers, focusing on how different we sometimes are and how the interface between our respective phases of a project (that is to say moving from a design phase into production) can sometimes become a battleground. I don’t believe it has to be a battleground. It’s actually more like being a dance partner – our steps are different, but as long as we know our own part and have a little knowledge of our partner’s steps, it all goes together to form a cohesive dance. Albeit with less spandex and fewer sequins (although that may depend on the project in question). As the process usually flows from design towards development, it’s most important that designers have a little knowledge of how the site is going to be built. At the specialist web development agency I’m part of, we find that designs that have been well considered from a technical perspective help to keep the project on track and on budget. Based on that experience, I’ve put together my checklist of things that designers should consider before handing their work over to a developer to build. Layout One rookie mistake made by traditionally trained designers transferring to the web is to forget a web browser is not a fixed medium. Unlike designing a magazine layout or a piece of packaging, there are lots of available options to consider. Should the layout be fluid and resize with the window, or should it be set to a fixed width? If it’s fluid, which parts expand and which not? If it’s fixed, should it sit in the middle of the window or to one side? If any part of the layout is going to be flexible (get wider and narrower as required), consider how any graphics are affected. Images don’t usually look good if displayed at anything other that their original size, so should they behave? If a column is going to get wider than it’s shown in the Photoshop comp, it may be necessary to provide separate wider versions of any background images. Text size and content volume A related issue is considering how the layout behaves with both different sizes of text and different volumes of content. Whilst text zooming rather than text resizing is becoming more commonplace as the default behaviour in browsers, it’s still a fundamentally important principal of web design that we are suggesting and not dictating how something should look. Designs must allow for a little give and take in the text size, and how this affects the design needs to be taken into consideration. Keep in mind that the same font can display differently in different places and platforms. Something as simple as Times will display wider on a Mac than on Windows. However, the main impact of text resizing is the change in how much vertical space copy takes up. This is particularly important where space is limited by the design (making text bigger causes many more problems than making text smaller). Each element from headings to box-outs to navigation items and buttons needs to be able to expand at least vertically, if not horizontally as well. This may require some thought about how elements on the page may wrap onto new lines, as well as again making sure to provide extended versions of any graphical elements. Similarly, it’s rare theses days to know exactly what content you’re working with when a site is designed. Many, if not most sites are designed as a series of templates for some kind of content management system, and so designs cannot be tweaked around any specific item of content. Designs must be able to cope with both much greater and much lesser volumes of content that might be thrown in at the lorem ipsum phase. Particular things to watch out for are things like headings (how do they wrap onto multiple lines) and any user-generated items like usernames. It can be very easy to forget that whilst you might expect something like a username to be 8-12 characters, if the systems powering your site allow for 255 characters they’ll always be someone who’ll go there. Expect them to do so. Again, if your site is content managed or not, consider the possibility that the structure might be expanded in the future. Consider how additional items might be added to each level of navigation. Whilst it’s rarely desirable to make significant changes without revisiting the site’s information architecture more thoroughly, it’s an inevitable fact of life that the structure needs a little bit of flexibility to change over time. Interactions with and without JavaScript A great number of sites now make good use of JavaScript to streamline the user interface and make everything just that touch more usable. Remember, though, that any developer worth their salt will start by building the interface without JavaScript, get it all working, and then layer that JavaScript on top. This is to allow for users viewing the site without JavaScript available or enabled in their browser. Designers need to consider both states of any feature they’re designing – how it looks and functions with and without JavaScript. If the feature does something fancy with Ajax, consider how the same can be achieved with basic HTML forms, links and intermediary pages. These all need to be designed, because this is how some of your users will interact with the site. Logged in and logged out states When designing any type of web application or site that has a membership system – that is to say users can create an account and log into the site – the design will need to consider how any element is presented in both logged in and logged out states. For some items there’ll be no difference, whereas for others there may be considerable differences. Should an item be hidden completely not logged out users? Should it look different in some way? Perhaps it should look the same, but prompt the user to log in when they interact with it. If so, what form should that prompt take on and how does the user progress through the authentication process to arrive back at the task they were originally trying to complete? Couple logged in and logged out states with the possible absence of JavaScript, and every feature needs to be designed in four different states: Logged out with JavaScript available Logged in with JavaScript available Logged out without JavaScript available Logged in without JavaScript available Fonts There are three main causes of war in this world; religions, politics and fonts. I’ve said publicly before that I believe the responsibility for this falls squarely at the feet of Adobe Photoshop. Photoshop, like a mistress at a brothel, parades a vast array of ropey, yet strangely enticing typefaces past the eyes of weak, lily-livered designers, who can’t help but crumble to their curvy charms. Yet, on the web, we have to be a little more restrained in our choice of typefaces. The purest solution is always to make the best use of the available fonts, but this isn’t always the most desirable solution from a design point of view. There are several technical solutions such as techniques that utilise Flash (like sIFR), dynamically generated images and even canvas in newer browsers. Discuss the best approach with your developer, as every different technique has different trade-offs, and this may impact the design in other ways. Messaging Any site that has interactive elements, from a simple contact form through to fully featured online software application, involves some kind of user messaging. By this I mean the error messages when something goes wrong and the success and thank-you messages when something goes right. These typically appear as the result of an interaction, so are easy to forget and miss off a Photoshop comp. For every form, consider what gets displayed to the user if they make a mistake or miss something out, and also what gets displayed back when the interaction is successful. What do they see and where do the go next? With Ajax interactions, the user doesn’t get any visual feedback of the site waiting for a response from the server unless you design it that way. Consider using a ‘waiting’ or ‘in progress’ spinner to give the user some visual feedback of any background processes. How should these look? How do they animate? Similarly, also consider the big error pages like a 404. With luck, these won’t often be seen, but it’s at the point that they are when careful design matters the most. Form fields Depending on the visual style of your site, the look of a browser’s default form fields and buttons can sometimes jar. It’s understandable that many a designer wants to change the way they look. Depending on the browser in question, various things can be done to style form fields and their buttons (although it’s not as flexible as most would like). A common request is to replace the default buttons with a graphical button. This is usually achievable in most cases, although it’s not easy to get a consistent result across all browsers – particularly when it comes to vertical positioning and the space surrounding the button. If the layout is very precise, or if space is at a premium, it’s always best to try and live with the browser’s default form controls. Whichever way you go, it’s important to remember that in general, each form field should have a label, and each form should have a submit button. If you find that your form breaks either of those rules, you should double check. Practical tips for handing files over There are a couple of basic steps that a design can carry out to make sure that the developer has the best chance of implementing the design exactly as envisioned. If working with Photoshop of Fireworks or similar comping tool, it helps to group and label layers to make it easy for a developer to see which need to be turned on and off to get to isolate parts of the page and different states of the design. Also, if you don’t work in the same office as your developer (and so they can’t quickly check with you), provide a PDF of each page and state so that your developer can see how each page should look aside from any confusion with quick layers are switched on or off. These also act as a handy quick reference that can be used without firing up Photoshop (which can kill both productivity and your machine). Finally, provide a colour reference showing the RGB values of all the key colours used throughout the design. Without this, the developer will end up colour-picking from the comps, and could potentially end up with different colours to those you intended. Remember, for a lot of developers, working in a tool like Photoshop is like presenting a designer with an SSH terminal into a web server. It’s unfamiliar ground and easy to get things wrong. Be the expert of your own domain and help your colleagues out when they’re out of their comfort zone. That goes both ways. In conclusion When asked the question of how to smooth hand-over between design and development, almost everyone who has experienced this situation could come up with their own list. This one is mine, based on some of the more common experiences we have at edgeofmyseat.com. So in bullet point form, here’s my checklist for handing a design over. Is the layout fixed, or fluid? Does each element cope with expanding for larger text and more content? Are all the graphics large enough to cope with an area expanding? Does each interactive element have a state for with and without JavaScript? Does each element have a state for logged in and logged out users? How are any custom fonts being displayed? (and does the developer have the font to use?) Does each interactive element have error and success messages designed? Do all form fields have a label and each form a submit button? Is your Photoshop comp document well organised? Have you provided flat PDFs of each state? Have you provided a colour reference? Are we having fun yet?",2008,Drew McLellan,drewmclellan,2008-12-01T00:00:00+00:00,https://24ways.org/2008/easing-the-path-from-design-to-development/,process 111,Geometric Background Patterns,"When the design is finished and you’re about to start the coding process, you have to prepare your graphics. If you’re working with a pattern background you need to export only the repeating fragment. It can be a bit tricky to isolate a fragment to achieve a seamless pattern background. For geometric patterns there is a method I always follow and that I want to share with you. Take for example a perfect 45° diagonal line pattern. How do you define this pattern fragment so it will be rendered seamlessly? Here is the method I usually follow to avoid a mismatch. First, zoom in so you see enough detail and you can distinguish the pixels. Select the Rectangular Marquee Selection tool and start your selection at the intersection of 2 different colors of a diagonal line. Hold down the Shift key while dragging so you drag a perfect square. Release the mouse when you reach the exact same intesection (as your starting) point at the top right. Copy this fragment (using Copy Merged: Cmd/Ctrl + Shift + C) and paste the fragment in a new layer. Give this layer the name ‘pattern’. Now hold down the Command Key (Control Key on Windows) and click on the ‘pattern’ layer in the Layers Palette to select the fragment. Now go to Edit > Define Pattern, enter a name for your pattern and click OK. Test your pattern in a new document. Create a new document of 600 px by 400px, hit Cmd/Ctrl + A and go to Edit > Fill… and choose your pattern. If the result is OK, you have created a perfect pattern fragment. Below you see this pattern enlarged. The guides show the boundaries of the pattern fragment and the red pixels are the reference points. The red pixels at the top right, bottom right and bottom left should match the red pixel at the top left. This technique should work for every geometric pattern. Some patterns are easier than others, but this, and the Photoshop pattern fill test, has always been my guideline. Other geometric pattern examples Example 1 Not all geometric pattern fragments are squares. Some patterns look easy at first sight, because they look very repetitive, but they can be a bit tricky. Zoomed in pattern fragment with point of reference shown: Example 2 Some patterns have a clear repeating point that can guide you, such as the blue small circle of this pattern as you can see from this zoomed in screenshot: Zoomed in pattern fragment with point of reference shown: Example 3 The different diagonal colors makes a bit more tricky to extract the correct pattern fragment. The orange dot, which is the starting point of the selection is captured a few times inside the fragment selection:",2008,Veerle Pieters,veerlepieters,2008-12-02T00:00:00+00:00,https://24ways.org/2008/geometric-background-patterns/,design 112,User Styling,"During the recent US elections, Twitter decided to add an ‘election bar’ as part of their site design. You could close it if it annoyed you, but the action wasn’t persistent and the bar would always come back like a bad penny. The solution to common browsing problems like this is CSS. ‘User styling’ (or the creepy ‘skinning’) is the creation of CSS rules to customise and personalise a particular domain. Aside from hiding adverts and other annoyances, there are many reasons for taking the time and effort to do it: Improving personal readability by changing text size and colour Personalising the look of a web app like GMail to look less insipid Revealing microformats Sport! My dreams of site skinning tennis are not yet fully realised, but it’ll be all the rage by next Christmas, believe me. Hopefully you’re now asking “But how? HOW?!”. The process of creating a site skin is roughly as follows: See something you want to change Find out what it’s called, and if any rules already apply to it Write CSS rule(s) to override and/or enhance it. Apply the rules So let’s get stuck in… See something Let’s start small with Multimap.com. Look at that big header – it takes up an awful lot of screen space doesn’t it? No matter, we can fix it. Tools Now we need to find out where that big assed header is in the DOM, and make overriding CSS rules. The best tool I’ve found yet is the Mac OS X app, CSS Edit. It utilises a slick ‘override stylesheets’ function and DOM Inspector. Rather than give you all the usual DOM inspection tools, CSS Edit’s is solely concerned with style. Go into ‘X-Ray’ mode, click an element, and look at the inspector window to see every style rule governing it. Click the selector to be taken to where it lives in the CSS. It really is a user styling dream app. Having said all that, you can achieve all this with free, cross platform tools – namely Firefox with the Firebug and Stylish extensions. We’ll be using them for these examples, so make sure you have them installed if you want to follow along. Using Firebug, we can see that the page is very helpfully marked up, and that whole top area is simply a div with an ID of header. Change Something When you installed Stylish, it added a page and brush icon to your status bar. Click on that, and choose Write Style > for Multimap.com. The other options allow you to only create a style for a particular part of a website or URL, but we want this to apply to the whole of Multimap: The ‘Add Style’ window then pops up, with the @-moz-document query at the top: @namespace url(http://www.w3.org/1999/xhtml); @-moz-document domain(""multimap.com"") { } All you need to do is add the CSS to hide the header, in between the curly brackets. @namespace url(http://www.w3.org/1999/xhtml); @-moz-document domain(""multimap.com"") { #header {display: none;} } A click of the preview button shows us that it’s worked! Now the map appears further up the page. The ethics of hiding adverts is a discussion for another time, but let’s face it, when did you last whoop at the sight of a banner? Make Something Better If we’re happy with our modifications, all we need to do is give it a name and save. Whenever you visit Multimap.com, the style will be available. Stylish also allows you to toggle a style on/off via the status bar menu. If you feel you want to share this style with the world, then userstyles.org is the place to do it. It’s a grand repository of customisations that Stylish connects with. Whenever you visit a site, you can see if anyone else has written a style for it, again, via the status bar menu “Find Styles for this Page”. Selecting this with “BBC News” shows that there are plenty of options, ranging from small layout tweaks to redesigns: What’s more, whenever a style is updated, Stylish will notify you, and offer a one-click process to update it. This does only work in Firefox and Flock, so I’ll cover ways of applying site styles to other browsers later. Specific Techniques Important! In the Multimap example there wasn’t a display specified on that element, but it isn’t always going to be that easy. You may have spent most of your CSS life being a good designer and not resorting to adding !important to give your rule priority. There’s no way to avoid this in user styling – if you’re overriding an existing rule it’s a necessity! Be prepared to be typing !important a lot. Star Selector The Universal Selector is a particularly useful way to start a style. For example, if we want to make Flickr use Helvetica before Arial (as they should’ve done!), we can cover all occurrences with just one rule: * {font-family: ""Helvetica Neue"", Helvetica, sans-serif !important;} You can also use it to select ‘everything within an element’, by placing it after the element name: #content * {font-family: ""Helvetica Neue"", Helvetica, sans-serif !important;} Swapping Images If you’re changing something a little more complex, such as Google Reader, then at some point you’ll probably want to change an . The technique for replacing an image involves: making your replacement image the background of the tag adding padding top and left to the size of you image to push the ‘top’ image away making the height and width zero. The old image is then pushed out of the way and hidden from view, allowing the replacement in the background to be revealed. Targeting the image may require using an attribute selector: img[src=""/reader/ui/3544433079-tree-view-folder-open.gif""] { padding: 16px 0 0 16px; width: 0 !important; height: 0 !important; background-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYA AAAf8/9hAAAABHNCSVQICAgIfAhkiAAAAAlwSFlzAAALEgAACxIB0t1+/AAAA Bx0RVh0U29mdHdhcmUAQWRvYmUgRmlyZXdvcmtzIENTM5jWRgMAAAAVdE VYdENyZWF0aW9uIFRpbWUAMjkvNi8wOJJ/BVgAAAG3SURBVDiNpZIhb5RBEIaf 2W+vpIagIITSBIHBgsGjEYQaFLYShcITDL+ABIPnh4BFN0GQNFA4Cnf3fbszL2L3 jiuEVLDJbCazu8+8Mzsmif9ZBvDy7bvXlni0HRe8eXL/zuPzABng62J5kFKaAQS QgJAOgHMB9vDZq+d71689Hcyw9LfAZAYdioE10VSJo6OPL/KNvSuHD+7dhU 0vHEsDUUWJChIlYJIjFx5BuMB2mJY/DnMoOJl/R147oBUR0QAm8LAGCOEh3IO ULiAl8jSOy/nPetGsbGRKjktEiBCEHMlQj4loCuu4zCXCi4lUHTNDtGqEiACTqAFSI OgAUAKv4bkWVy2g6tAbJtGy0TNugM3HADmlurKH27dVZSecxjboXggiAsMItR h99wTILdewYRpXVJWtY85k7fPW8e1GpJFJacgesXs6VYYomz9G2yDhwPB7NEB BDAMK7WYJlisYVBCpfaJBeB+eocFyVyAgCaoMCTJSTOOCWSyILrAnaXpSexRsx GGAZ0AR+XT+5fjzyfwSpnUB/1w64xizVI/t6q3b+58+vJ96mWtLf9haxNoc8M v7N3d+AT4XPcFIxghoAAAAAElFTkSuQmCC) no-repeat !important; } Woah boy! What was all that gubbins in the background-image? It was a Data URI, and you can create these easily with Hixie’s online tool. It’s simply the image translated into text so that it can be embedded in the CSS, cutting down on the number of http requests. It’s also a necessity with Mozilla browsers, as they don’t allow user CSS to reference images stored locally. Converting images to URI’s avoids this, as well as making a style easily portable – no images folder to pass around. Don’t forget all your other CSS techniques at your disposal: inserting your own content with :before and :after pseudo classes, make elements semi-transparent with opacity and round box corners without hacking . You can have fun, and for once, enjoy the freedom of not worrying about IE! User styling without Stylish Instead of using the Stylish extension, you can add rules to the userContent.css file, or use @import in that file to load a separate stylesheet. You can find this is in /Library/Application Support/Camino/chrome/ on OS X, or C/Program Files/Mozilla Firefox/Chrome on Windows. This is only way to apply user styles in Camino, but what about other browsers? Opera & Omniweb: Both allow you to specify a custom CSS file as part of the site’s preferences. Opera also allows custom javascript, using the same syntax as Greasemonkey scripts (more on that below) Safari There are a few options here: the PithHelmet and SafariStand haxies both allow custom stylesheets, or alternatively, a Greasemonkey style user script can employed via GreaseKit. The latter is my favoured solution on my Helvetireader theme, as it can allow for more prescriptive domain rules, just like the Mozilla @-moz-document method. User scripts are also the solution supported by the widest range of browsers. What now? Hopefully I’ve given you enough information for you to be able start making your own styles. If you want to go straight in and tackle the ‘Holy Grail’, then off with you to GMail – I get more requests to theme that than anything else! If you’re a site author and want to encourage this sort of tom foolery, a good way is to provide a unique class or ID name with the body tag:
This makes it very easy to write rules that only apply to that particular site. If you wanted to use Safari without any of the haxies mentioned above, this method means you can include rules in a general CSS file (chosen via Preferences > Advanced > Stylesheet) without affecting other sites. One final revelation on user styling – it’s not just for web sites. You can tweak the UI of Firefox itself with the userChrome.css. You’ll need to use the in-built DOM Inspector instead of Firebug to inspect the window chrome, instead of a page. Great if you want to make small tweaks (changing the size of tab text for example) without creating a full blown theme.",2008,Jon Hicks,jonhicks,2008-12-03T00:00:00+00:00,https://24ways.org/2008/user-styling/,process 104,Sitewide Search On A Shoe String,"One of the questions I got a lot when I was building web sites for smaller businesses was if I could create a search engine for their site. Visitors should be able to search only this site and find things without the maintainer having to put “related articles” or “featured content” links on every page by hand. Back when this was all fields this wasn’t easy as you either had to write your own scraping tool, use ht://dig or a paid service from providers like Yahoo, Altavista or later on Google. In the former case you had to swallow the bitter pill of computing and indexing all your content and storing it in a database for quick access and in the latter it hurt your wallet. Times have moved on and nowadays you can have the same functionality for free using Yahoo’s “Build your own search service” – BOSS. The cool thing about BOSS is that it allows for a massive amount of hits a day and you can mash up the returned data in any format you want. Another good feature of it is that it comes with JSON-P as an output format which makes it possible to use it without any server-side component! Starting with a working HTML form In order to add a search to your site, you start with a simple HTML form which you can use without JavaScript. Most search engines will allow you to filter results by domain. In this case we will search “bbc.co.uk”. If you use Yahoo as your standard search, this could be: The Google equivalent is: In any case make sure to use the ID term for the search term and site for the site, as this is what we are going to use for the script. To make things easier, also have an ID called customsearch on the form. To use BOSS, you should get your own developer API for BOSS and replace the one in the demo code. There is click tracking on the search results to see how successful your app is, so you should make it your own. Adding the BOSS magic BOSS is a REST API, meaning you can use it in any HTTP request or in a browser by simply adding the right parameters to a URL. Say for example you want to search “bbc.co.uk” for “christmas” all you need to do is open the following URL: http://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&format=xml&appid=YOUR-APPLICATION-ID Try it out and click it to see the results in XML. We don’t want XML though, which is why we get rid of the format=xml parameter which gives us the same information in JSON: http://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&appid=YOUR-APPLICATION-ID JSON makes most sense when you can send the output to a function and immediately use it. For this to happen all you need is to add a callback parameter and the JSON will be wrapped in a function call. Say for example we want to call SITESEARCH.found() when the data was retrieved we can do it this way: http://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&callback=SITESEARCH.found&appid=YOUR-APPLICATION-ID You can use this immediately in a script node if you want to. The following code would display the total amount of search results for the term christmas on bbc.co.uk as an alert: However, for our example, we need to be a bit more clever with this. Enhancing the search form Here’s the script that enhances a search form to show results below it. SITESEARCH = function(){ var config = { IDs:{ searchForm:'customsearch', term:'term', site:'site' }, loading:'Loading results...', noresults:'No results found.', appID:'YOUR-APP-ID', results:20 }; var form; var out; function init(){ if(config.appID === 'YOUR-APP-ID'){ alert('Please get a real application ID!'); } else { form = document.getElementById(config.IDs.searchForm); if(form){ form.onsubmit = function(){ var site = document.getElementById(config.IDs.site).value; var term = document.getElementById(config.IDs.term).value; if(typeof site === 'string' && typeof term === 'string'){ if(typeof out !== 'undefined'){ out.parentNode.removeChild(out); } out = document.createElement('p'); out.appendChild(document.createTextNode(config.loading)); form.appendChild(out); var APIurl = 'http://boss.yahooapis.com/ysearch/web/v1/' + term + '?callback=SITESEARCH.found&sites=' + site + '&count=' + config.results + '&appid=' + config.appID; var s = document.createElement('script'); s.setAttribute('src',APIurl); s.setAttribute('type','text/javascript'); document.getElementsByTagName('head')[0].appendChild(s); return false; } }; } } }; function found(o){ var list = document.createElement('ul'); var results = o.ysearchresponse.resultset_web; if(results){ var item,link,description; for(var i=0,j=results.length;iThis hCard created with the hCard creator.
