Custom Menu Style Issue in Twentyeleven Child Theme

I am building a child theme using the TwentyEleven theme as a parent. I have a custom menu and have styled the anchor links to highlight using the following css.

#access .current_page_item > a,
#access .current_page_ancestor > a {
font-weight:bold;
color:#FFFF00;
}

The problem is my menu has pages and categories listed. The page links are styled per the above css, but the links that are categories aren’t styled by the above code and I can’t find out where to style it so they will appear the same way.

I’d appreciate any heads up on where the style code is for that. I can’t find it in the parent style sheet.
