I suggest that you make friends with firebug (a firefox exgtension that provides debugging of browser CSS. It will let you find the elements you want to target, and how youe css is being applied.
First, make sure you are using a Child Theme to make your CSS edits.
I agree with Ross that you’ll want to look into using the browser plugin Firebug, using that you can directly see and test CSS in the browser.
The Twenty Twelve footer background can be changed like this, but you’ll most likely want to make some additional changes as the footer does not stretch 100% across the screen due to some padding.
footer[role=”contentinfo”] {
background: none repeat scroll 0 0 #eeeeee;
}
hi there–
am having scads of fun with firebug; i tried it out a couple years ago when i was first wrestling with CSS, but feel more comfortable with it now. and bretWP, thanks so much: putting that code in the child’s style sheet worked perfectly. i don’t know why i didn’t see the footer background code, but i didn’t. Thank you both again!
