Avatars and 320px width screen

My latest adventure has me working on the "Set as Avatar" option.

I am just not understanding the whole selection process when selecting an avatar.

I see all these divs with absolute widths.  I really need to change those to 100%.

I tried it with firebug, without much success.

Any ideas?

Thanks!

I'm having trouble understanding your post/question.  Please explain again and with a little more detail.

Here's a screenshot to help.

Full screen looks fine.

in the 320px wide screen you can see the selector way too big.
