CSS animations is a proposed module for Cascading Style Sheets that allows the animation of HTML document elements using CSS.
While the pseudo-class
:hoverhas been used to generate rich animations for years, the extensions of CSS in the realm of animation were minimal until the late 2000s decade. As early as 2007, WebKit has been launched to include CSS animation, transitions, and transforms as features of WebKit. It has also been proposed by the CSS in the context of CSS3, the W3C ( World Wide Web Consortium ).
As of June 2011, Firefox 5 includes CSS animations support.  CSS animation is also available as a module in the nightly builds of Google Chrome , Safari 4 and 5 and Safari for iOS (iPhone, iPod Touch, iPad), Android versions 2.x and 3.x, the BlackBerry OS 6 web browser, with the
-webkit-prefix.   It is also used in iTunes 9 to support iTunes LP files.
