Parallax scrolling is pretty awesome, but it usually takes some jQuery to pull it off.
But, not with skrollr!
Check it out:
By using HTML5 and CSS3, skrollr is actually more than just “parallax.” it’s actually a “full-fledged animation library.”
skrollr allows you to animate any CSS property of any element depending on the horizontal scrollbar position. All you need to do is define key frames for each element at certain points in top offset.
A very interesting concept.
Take a look at the code and download it from Github from the skrollr demo site.
