Font size not defined in #navMain

Still trying to change font size in horizontal bar for categories on main page. Not found in #navMain. Can it just be inserted or am I looking in the wrong place? Tried changing other vectors like line-height or padding. Thanks! view at http: //www.naicsfurniture.com

#navMain ul, #navSupp ul, #navCatTabs ul {
margin: 0;
padding: 0.5em 0em;
list-style-type: none;
text-align: center;
line-height: 1.5em;
}

#navMain ul li, #navSupp ul li, #navCatTabs ul li {
display: inline;
}

#navMain ul li a, #navSupp ul li a, #navCatTabs ul li a {
text-decoration: none;
padding: 0em 0.5em;
margin: 0;
color: #ffffff;
white-space: nowrap;
}

Add this to your stylesheet and adjust to suit

#navCatTabsWrapper {
        font-size: 1.2em;
        }

That worked just great. Thank you!
