OK, that is "light and lucid". If it is/was 3 columns your stylesheet is main.css. If it is 2 columns then you also will have a stylesheet named altskin.css. In addition, there are stylesheets for the various web browsers out there, but usually these don't need to be messed with (but still be aware of them).

The bit of code you posted does not look like it is from the original file as it has "style="display:block;" as part of the .tpl instead of adding it to the "subcat-desc" style in the stylesheet. Anyway, look for the style associated with what you are working on in main.css (and altskin.css if you are using it as well). Sometimes it takes a little digging, but it is much better than altering the .tpl.
