Change Category Navigation Font to Capitalized

Site URL: http://www.amovintage.com

Hi, 

I would like my category navigation links to display in capitals instead of following the rest of the sites formula, is there a way to do this? Where it says Tops, bottoms etc

Thankyou x

Add to Design > Custom CSS

/* nav links uppercase */
ul.nested-category-children a {
    text-transform: uppercase;
}
