SidePosts css background color?

What would I put in to the css file and where?

Given that no one knows your site, it’s impossible to say. So a site url could come in quite handy about now…

Sorry. Didn’t think looking at the site would be handy. It is just a PTO site for our schools. It is at chagrinfallspto.org . I would like to use Sideposts to display current events on the sidebar – but nothing shows up well with the corkboard background image. I need to have a background for the lettering.

Does that help?

Thanks for taking the time to respond. I know it is a basic question. Any direction would be appreciated.

By “Sideposts”, I’m assuming you mean the right-hand sidebar. That theme doesn’t lend itself to easy editing. Try editing style.css and changing:

#sidebar {
color:#FFFFFF;
float:right;
font-size:14pt;
width:200px;
}

to

#sidebar {
background:#fff;
color:#606060;
float:right;
font-size:14pt;
width:210px;
}

Then add:

#sidebar a {color:#606060;}
