As you have probably heard by now, CSS3 animations are a powerful tool, which enables you to create animations which run without the need of applying additional scripting to the page. What is even better, in the next generation of browsers we will have even more powerful tools, including 3D transformations (already present in Safari).
But what difference does it make for us today? At the moment only three browsers give you the ability to animate CSS properties – Chrome, Safari and Opera, which together take up only a small part of the browser market. Firefox is expected to soon join the club, and with the impending release of IE9, it suddenly makes sense to start leveraging this technique.
So today we are making something practical – a simple CSS3 animated navigation menu, which degrades gracefully in older browsers and is future-proofed to work with the next generation of browsers.
