In your stylesheet, locate
Code:
#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;
}
Code:
#navSupp ul li a, #navCatTabs ul li a {
text-decoration: none;
padding: 0em 0.5em;
margin: 0;
color: #ffffff;
white-space: nowrap;
}
#navMain ul li a {
text-decoration: none;
padding: 0em 0.5em;
margin: 0;
color: #ffffff;
white-space: nowrap;
font-size: 1.95em;
font-weight: bold;
}
Adjust the font size (line in red) as desired. 1.95em is pretty big.
If you're using Firefox with the web developer add on, you can try this on the fly and adjust color and size as you want before making it permanent.
