Convert jquery scroll event animation to css

Question

How would I go about altering this code:

$(window).scroll(function(i){
var scrollVar = $(window).scrollTop();
$('section#about .inner').children('h2').css({'top': .7*scrollVar });
$('section#about .inner').children('h2').css({'opacity':( 100-scrollVar )/100});
})

to an add/remove class in order to use css3 animation? The jQuery animation is really janky. Thanks for any insigh

If you want to align the image, you just have to calculate the position according to its size.

ctx.drawImage(img, c.width - img.width/2, c.height - img.height/2,c.width/2, c.height/2);

In the example above, the image is aligned to bottom right corner. Btw, I divided it by 2, so you can clearly see the alignment.
