HTML5, CSS3, JS Demos, Creations and Experiments | CSSDeck Browserhacks HTML5 und CSS3 mit Hilfe von Modernizr verwenden Modernizr ist eine praktische Open Source JavaScript-Library, um schon heute HTML5 und CSS3 Elemente für Webseiten-Projekte nutzen zu können. Das Script funktioniert eigentlich recht einfach. Es stellt fest, welche HTML5 und CSS3-Funktionen der jeweils verwendete Browser unterstützt und welche nicht, und fügt dann automatisch entsprechende CSS-Klassen in den html-Tag der Webseite ein. Mit Hilfe dieser CSS-Klassen kannst du dann in deinem Stylesheet arbeiten, und entsprechende Styles für moderne Browser, sowie Fallback-Lösungen für ältere Browser definieren. Modernizr ist also besonders hilfreich, um moderne Features wie @font-face, Multiple Backgrounds oder HTML5-Video zu verwenden, und dennoch alternative CSS-Styles für Browser anbieten zu können, die diese Features noch nicht unterstützen. 1. Um Modernizr verwenden zu können, musst du dir als erstes das aktuelle Script (derzeit 1.6, letztes Update am 25.10.2010) auf der Webseite von Modernizr herunterladen. 2. 3. 4.
The Definitive Guide to CSS Transitions Back in the golden days of the web, we had a little thing called Flash to help us make the web a dynamic, fun, interactive place. But, Flash is being used less and less. Of course, in certain environments it can still be put to amazing use, but in today’s web environment you need CSS to get the job done. One of the easiest ways to give your site a near-instant facelift is to bring CSS3 transitions to the table (pun intended). Drop this into an HTML document and check it out: Yeah, I know gray boxes aren’t all that exciting, but the point is that the transitions on the box to the right are more interesting and give the design a more polished feel. Pseudo-Classes for CSS Transitions The key to making CSS transitions work is through the use of pseudo-classes. Here we have the CSS element for a link and the pseudo-class “hover” for when the mouse is over the link. Some other important pseudo-classes you need to know for CSS transitions include: Introducing CSS Transitions Beyond :hover and Links
CSS3 Patterns Gallery Browser support The patterns themselves should work on Firefox 3.6+, Chrome, Safari 5.1, Opera 11.10+ and IE10+. However, implementation limitations might cause some of them to not be displayed correctly even on those browsers (for example at the time of writing, Gecko is quite buggy with radial gradients). Also, this gallery won’t work in Firefox 3.6 and IE10, even though they support gradients, due to a JavaScript limitation. Submission guidelines If you have a new pattern to submit, please send a pull request. Does it present a new technique? CSS Background Animations Background animations are an awesome touch when used correctly. In the past, I used MooTools to animate a background position. Luckily these days CSS animations are widely supported enough to rely on them to take over JavaScript-based animation tasks. The following simple CSS snippet animates the background image (via background position) of a given element. We'll use CSS animations instead of transitions for this effect: With the animation code in place, now it's time to apply it to an element with a background image: The cloud background image within the sample element will elegantly scroll from left to right over a duration of 40 seconds, seamlessly repeating an infinite number of times. How epic is it that we don't need to use JavaScript to manage these animations anymore?
