How do I control caption background?

Screenshots are of no use. What might help is a link to a page demonstrating the problem.

Oh, boy … I feel like one of the Hardy Boys!! ??

( But I’ll feel like a schmuck, if this doesn’t work )

Try this… find this in your style sheet:

.wp-caption
{
border: 1px solid #ddd;
background-color: #f3f3f3;
padding-top: 4px;
margin: 10px;
}

Try changing it to this:

.wp-caption
{
border: 1px solid #000;
background-color: #000;
padding-top: 4px;
margin: 10px;
}

See if that pushes it in the right direction for you.

Thanks! It worked perfectly!

Sorry for the newbieness, but the key for me was to look in the
Appearance -> Editor-> Stylesheet (style.css).

Thanks for the timely help!

You’re welcome.

no wp-caption
in any style sheet of my Theme, where could i alternatively find something that makes the caption or thumbs background??
P.S. my Theme uses something called “prettyPhoto” but i have no clue if this applies to any of the posts images at all nor can i find anything related to my issue in that style sheet either
