using CSS styling with wp-blogroll

?Below is an excerpt which i found before using the wp-blogroll plugin.The plugin provides a Title, Category Headers and Site Links for each Category. I was able to get the plugin working but found that the link title font-size was considerably larger than any of the headers. (It was the same size as the Title) For esthetic reasons I wanted the link Names to be smaller than the category headers.
Note the comments made below concerning CSS. I have tried virtually everything that i can think of (using the CSS insert using Atahualpa 3.4.6) but nothing seems to work. I also viewed the php file that came with the plugin and i could not find any reference to CSS target styling code (the code which writes the category headers and site links to the screen ?) Despite the hints of linkcat and brlink the were given below I have had no luck. Can someone go a step further and actually show some of the CSS styling rules or tell me where I can find the target code (which writes to the screen) in the source. Your help would be appreciated. Also the showdesc=1 variable in the short code shows both the hover text and text below the link – only hover text is desired.
