In new, standardized unprefixed syntax, you should be using "to" plus the side you want the gradient to end at.
background-image: linear-gradient(to bottom, #000000, #FFFFFF);
background-image: linear-gradient(top, #000000, #FFFFFF); /* this is wrong and will not work! */
cool, got time to send in a patch? might take a while before I can make the change myself.
Update to latest CSS3 gradient spec
The latest CSS3 spec at http://dev.w3.org/csswg/css3-images/#linear-gradients
specifies that linear gradients should be specified with `to <end-point>` rather
This patch makes that change as well as updates the example.css
Fixes issue #6
