{"rowid": 328, "title": "Swooshy Curly Quotes Without Images", "contents": "The problem\n\nTake a quote and render it within blockquote tags, applying big, funky and stylish curly quotes both at the beginning and the end without using any images \u2013 at all.\n\nThe traditional way\n\nFeint background images under the text, or an image in the markup housed in a little float. Often designers only use the opening curly quote as it\u2019s just too difficult to float a closing one.\n\nWhy is the traditional way bad?\n\nWell, for a start there are no actual curly quotes in the text (unless you\u2019re doing some nifty image replacement). Thus with CSS disabled you\u2019ll only have default blockquote styling to fall back on. Secondly, images don\u2019t resize, so scaling text will have no affect on your graphic curlies.\n\nThe solution\n\nUse really big text. Then it can be resized by the browser, resized using CSS, and even be restyled with a new font style if you fancy it. It\u2019ll also make sense when CSS is unavailable.\n\nThe problem\n\nCreating \u201cDrop Caps\u201d with CSS has been around for a while (Big Dan Cederholm discusses a neat solution in that first book of his), but drop caps are normal characters \u2013 the A to Z or 1 to 10 \u2013 and these can all be pulled into a set space and do not serve up a ton of whitespace, unlike punctuation characters.\n\nCurly quotes aren\u2019t like traditional characters. Like full stops, commas and hashes they float within the character space and leave lots of dead white space, making it bloody difficult to manipulate them with CSS. Styles generally fit around text, so cutting into that character is tricky indeed. Also, all that extra white space is going to push into the quote text and make it look pretty uneven. This grab highlights the actual character space:\n\n\n\nSee how this is emphasized when we add a normal alphabetical character within the span. This is what we\u2019re dealing with here:\n\n\n\nThen, there\u2019s size. Call in a curly quote at less than 300% font-size and it ain\u2019t gonna look very big. The white space it creates will be big enough, but the curlies will be way too small. We need more like 700% (as in this example) to make an impression, but that sure makes for a big character space.\n\nPrepare the curlies\n\nFirstly, remove the opening \u201c from the quote. Replace it with the opening curly quote character entity \u201c. Then replace the closing \u201c with the entity reference for that, which is \u201d. Now at least the curlies will look nice and swooshy.\n\nAdd the hooks\n\nTwo reasons why we aren\u2019t using :first-letter pseudo class to manipulate the curlies. Firstly, only CSS2-friendly browsers would get what we\u2019re doing, and secondly we need to affect the last \u201cletter\u201d of our text also \u2013 the closing curly quote.\n\nSo, add a span around the opening curly, and a second span around the closing curly, giving complete control of the characters:\n\n
\u201cSpeech marks. Curly quotes. That annoying thing cool people do with their fingers to emphasize a buzzword, shortly before you hit them.\u201d\n\nSo far nothing will look any different, aside form the curlies looking a bit nicer. I know we\u2019ve just added extra markup, but the benefits as far as accessibility are concerned are good enough for me, and of course there are no images to download.\n\nThe CSS\n\nOK, easy stuff first. Our first rule .bqstart floats the span left, changes the color, and whacks the font-size up to an exuberant 700%. Our second rule .bqend does the same tricks aside from floating the curly to the right.\n\n.bqstart {\n float: left;\n font-size: 700%;\n color: #FF0000;\n }\n\n .bqend {\n float: right;\n font-size: 700%;\n color: #FF0000;\n }\n\nThat gives us this, which is rubbish. I\u2019ve highlighted the actual span area with outlines:\n\n\n\nNote that the curlies don\u2019t even fit inside the span! At this stage on IE 6 PC you won\u2019t even see the quotes, as it only places focus on what it thinks is in the div. Also, the quote text is getting all spangled.\n\nFiddle with margin and padding\n\nThink of that span outline box as a window, and that you need to position the curlies within that window in order to see them. By adding some small adjustments to the margin and padding it\u2019s possible to position the curlies exactly where you want them, and remove the excess white space by defining a height:\n\n.bqstart {\n float: left;\n height: 45px;\n margin-top: -20px;\n padding-top: 45px;\n margin-bottom: -50px;\n font-size: 700%;\n color: #FF0000;\n }\n\n .bqend {\n float: right;\n height: 25px;\n margin-top: 0px;\n padding-top: 45px;\n font-size: 700%;\n color: #FF0000;\n }\n\nI wanted the blocks of my curlies to align with the quote text, whereas you may want them to dig in or stick out more. Be aware however that my positioning works for IE PC and Mac, Firefox and Safari. Too much tweaking seems to break the magic in various browsers at various times. Now things are fitting beautifully:\n\nI must admit that the heights, margins and spacing don\u2019t make a lot of sense if you analyze them. This was a real trial and error job. Get it working on Safari, and IE would fail. Sort IE, and Firefox would go weird.\n\nFinished\n\nThe final thing looks ace, can be resized, looks cool without styles, and can be edited with CSS at any time. Here\u2019s a real example (note that I\u2019m specifying Lucida Grande and then Verdana for my curlies):\n\n \u201cSpeech marks. Curly quotes. That annoying thing cool people do with their fingers to emphasize a buzzword, shortly before you hit them.\u201d\n\nBrowsers happy\n\nAs I said, too much tweaking of margins and padding can break the effect in some browsers. Even now, Firefox insists on dropping the closing curly by approximately 6 or 7 pixels, and if I adjust the padding for that, it\u2019ll crush it into the text on Safari or IE. Weird. Still, as I close now it seems solid through resizing tests on Safari, Firefox, Camino, Opera and IE PC and Mac. Lovely.\n\nIt\u2019s probably not perfect, but together we can beat the evil typographic limitations of the web and walk together towards a brighter, more aligned world.

But since it relies heavily on floats for the positioning of its tabs, we\u2019re constrained to either left- or right-hand navigation. But what if we need a bit more flexibility? What if we need to place our navigation in the center?\n\nStyling the li as a floated block does give us a great deal of control over margin, padding, and other presentational styles. However, we should learn to love the inline box \u2013 with it, we can create a flexible, centered alternative to floated navigation lists.\n\nHumble Beginnings\n\nDo an extra shot of \u2018nog, because you know what\u2019s coming next. That\u2019s right, a simple unordered list:\n\n \n\nIf we were wedded to using floats to style our list, we could easily fix the width of our ul, and trick it out with some margin: 0 auto; love to center it accordingly. But this wouldn\u2019t net us much flexibility: if we ever changed the number of navigation items, or if the user increased her browser\u2019s font size, our design could easily break.\n\nInstead of worrying about floats, let\u2019s take the most basic approach possible: let\u2019s turn our list items into inline elements, and simply use text-align to center them within the ul:\n\n#navigation ul, #navigation ul li {\n list-style: none;\n margin: 0;\n padding: 0;\n}\n\n#navigation ul {\n text-align: center;\n}\n\n#navigation ul li {\n display: inline;\n margin-right: .75em;\n}\n\n#navigation ul li.last {\n margin-right: 0;\n}\n\nOur first step is sexy, no? Well, okay, not really \u2013 but it gives us a good starting point. We\u2019ve tamed our list by removing its default styles, set the list items to display: inline, and centered the lot. Adding a background color to the links shows us exactly how the different elements are positioned.\n\nNow the fun stuff.\n\nInline Elements, Padding, and You\n\nSo how do we give our links some dimensions? Well, as the CSS specification tells us, the height property isn\u2019t an option for inline elements such as our anchors. However, what if we add some padding to them?\n\n#navigation li a {\n padding: 5px 1em;\n}\n\nI just love leading questions. Things are looking good, but something\u2019s amiss: as you can see, the padded anchors seem to be escaping their containing list.\n\nThankfully, it\u2019s easy to get things back in line. Our anchors have 5 pixels of padding on their top and bottom edges, right? Well, by applying the same vertical padding to the list, our list will finally \u201ccontain\u201d its child elements once again.\n\n\u2019Tis the Season for Tabbing\n\nNow, we\u2019re finally able to follow the \u201cSliding Doors\u201d model, and tack on some graphics:\n\n#navigation ul li a {\n background: url(\"tab-right.gif\") no-repeat 100% 0;\n color: #06C;\n padding: 5px 0;\n text-decoration: none;\n}\n\n#navigation ul li a span {\n background: url(\"tab-left.gif\") no-repeat;\n padding: 5px 1em;\n}\n\n#navigation ul li a:hover span {\n color: #69C;\n text-decoration: underline;\n}\n\nFinally, our navigation\u2019s looking appropriately sexy. By placing an equal amount of padding on the top and bottom of the ul, our tabs are properly \u201ccontained\u201d, and we can subsequently style the links within them.\n\n\n\nBut what if we want them to bleed over the bottom-most border? Easy: we can simply decrease the bottom padding on the list by one pixel, like so.\n\nA Special Note for Special Browsers\n\nThe Mac IE5 users in the audience are likely hopping up and down by now: as they\u2019ve discovered, our centered navigation behaves rather annoyingly in their browser. As Philippe Wittenbergh has reported, Mac IE5 is known to create \u201cphantom links\u201d in a block-level element when text-align is set to any value but the default value of left. Thankfully, Philippe has documented a workaround that gets that [censored] venerable browser to behave. Simply place the following code into your CSS, and the links will be restored to their appropriate width:\n\n/**//*/\n#navigation ul li a {\n display: inline-block;\n white-space: nowrap;\n width: 1px;\n}\n/**/\n\nIE for Windows, however, displays an extra kind of crazy. The padding I\u2019ve placed on my anchors is offsetting the spans that contain the left curve of my tabs; thankfully, these shenanigans are easily straightened out:\n\n/**/\n* html #navigation ul li a {\n padding: 0;\n}\n/**/\n\nAnd with that, we\u2019re finally finished.\n\nAll set.\n\nAnd that\u2019s it.

Used well, Ajax brings a web interface much closer to the experience of a desktop app, and can turn a bear of an task into a pleasurable activity.\n\nBut it\u2019s really hard, right? It involves all the nasty JavaScript that no one ever does often enough to get really good at, and the browser support is patchy, and urgh it\u2019s just so much damn effort. Well, the good news is that \u2013 ta-da \u2013 it doesn\u2019t have to be a headache. But man does it still look impressive. Here\u2019s how to amaze your friends.\n\nIntroducing prototype.js\n\nPrototype is a JavaScript framework by Sam Stephenson designed to help make developing dynamic web apps a whole lot easier. In basic terms, it\u2019s a JavaScript file which you link into your page that then enables you to do cool stuff.\n\nThere\u2019s loads of capability built in, a portion of which covers our beloved Ajax. The whole thing is freely distributable under an MIT-style license, so it\u2019s good to go. What a nice man that Mr Stephenson is \u2013 friends, let us raise a hearty cup of mulled wine to his good name. Cheers! sluurrrrp.\n\nFirst step is to download the latest Prototype and put it somewhere safe. I suggest underneath the Christmas tree.\n\nCutting to the chase\n\nBefore I go on and set up an example of how to use this, let\u2019s just get to the crux. Here\u2019s how Prototype enables you to make a simple Ajax call and dump the results back to the page:\n\nvar url = 'myscript.php';\nvar pars = 'foo=bar';\nvar target = 'output-div';\t\nvar myAjax = new Ajax.Updater(target, url, {method: 'get', parameters: pars});\n\nThis snippet of JavaScript does a GET to myscript.php, with the parameter foo=bar, and when a result is returned, it places it inside the element with the ID output-div on your page.\n\nKnocking up a basic example\n\nSo to get this show on the road, there are three files we need to set up in our site alongside prototype.js. Obviously we need a basic HTML page with prototype.js linked in. This is the page the user interacts with. Secondly, we need our own JavaScript file for the glue between the interface and the stuff Prototype is doing. Lastly, we need the page (a PHP script in my case) that the Ajax is going to make its call too.\n\nSo, to that basic HTML page for the user to interact with. Here\u2019s one I found whilst out carol singing:\n\n\n\n\n \n
