Header Hyperlink Question

[kvanorsdel]

SMF Version: SMF 1.0.7
I have a header on my forum and it is hyperlinked back to my main page however the headerlogo has a purple/blue box around it for an active or visited link.  Where do I change that so it can still be a link but not have the Purple/Blue box, I'm using Black22 and my colors are Black green and yellow.  I'd like the logo to just have a black box around if it possible.

Thanks

Can you provide a link to your forum so we can see it?

The file you would probably want to edit is Themes/theme_name/style.css and possibly Themes/theme_name/index.template.php
