zoid technologies has an animated page header shown only on the index page using css3 animations.
behind the scenes, I copy-pasted the two effects I wanted (lightspeedin and rubberband) out of animate.css into index.css on www.zoidweb, which is why it works only on the index page. I found a decent video tutorial regarding animate.css after this feature was added to zoidweb.
I found some code on the net that suggested using window.onload() plus a custom css style to start animations after the page has been loaded. so far it seems to be working well.
