CSS Animations
CSS Animations is a proposed module for Cascading Style Sheets that allows for the animation of XML elements using CSS.
Storia
While the pseudo-class :hover has been used to generate rudimentary animations for years, extensions of CSS into the realm of animation were minimal until the late 2000s. As early as 2007, WebKit had announced its intention to include CSS animation, transitions, and transforms as features of WebKit. It also announced the implementation of both implicit and explicit animation through CSS in February 2009. CSS animation has also been put forth as a feature of CSS3, the ongoing draft specification managed by the W3C.
Supporto del browser
As of June 2011, Firefox 5 includes CSS Animation support.[1] CSS animation is also available as a module in the nightly builds of WebKit as well as Google Chrome, Safari 4 and 5 and Safari for iPhone, Android 2.x and 3.x, the RIM OS6 web browser, with the -webkit- prefix.[2][3] It is also used in iTunes 9 to support iTunes LP files.
Polemica
The specification of CSS animation has drawn concern from those who prefer animation through JavaScript[4] or, to a lesser-used extent, SMIL; others have claimed that it is a move by Apple Inc., the main sponsor of the WebKit project, to sidestep the inclusion of Adobe Flash (and the incumbent Flash animations) on the company's iPhone OS line of mobile devices which use Safari.[5][6][7]
