To center the menu text in a child theme of Twenty Eleven.
I end up with this... http://www.homemusicgear.com
It's not quite centered (padding somewhere?)
And there's a separate line that goes all the way across the page (you can see it when you hover over a button).
Ideas on how to fix it? I want the menu text to be centered and the hover gray to cover the whole block when hovering.
I know just enough CSS to be dangerous.
Ideas?
Thank you so much in advance!
