I'm absolutely not clear why the percentage based animation actually works in Firefox (and incidentally, Presto based Opera 12.x). And Eric notes it doesn't seem to work in IE 11 (and IE 10?). That seems correct per spec to me. That is pure CSS 2.1: http://www.w3.org/TR/CSS21/visuren.html#position-props specifically: > > Percentages: refer to height of containing block In the test case, the height of the containing block (.wrapper2) has a value of 'auto', which means that 'top' can't be computed. The demo would work in WebKit if the containing block has a specified height (e.g. 10em) or the animated box (.content) is position: absolute.
