Any preferences on how things resize? It'd probably be best if things retained their proportions. Depending on your resolution and the image, things may be distorted.

I'd say make the background repeating on both the x and y, if you look at my profile for an example, it looks a bit silly.

I think "cover" would be better than "repeat".

Technically you're not doing cover anyways because the background-size is set to 100% 100%.

Code:

background-size: cover;

(not to say that looks better than 100% though)
