2011 Theme Tag Line Font

You’ll need to post a link to your site for help with CSS issues.

Ah, now I see why you were having trouble with this (per your other thread) – you’re using the dark.css option for twentyeleven – and that stylesheet gets loaded after your child theme one. So one way around that is to use the !important rule in CSS to override the dark.css. You can see if that’s where the styles are from by using Firebug – look for the stylesheet on the right side of the styles. So try this:

#site-description {
    color: #858585;
    font-size: XXpx !important;
}

Yeah, the dark.css exception to the rule is annoying :/ !
