I strongly suggest that now is the time to take a look at CSS (Cascading Style Sheets). CSS enables you to decouple presentation (the way it looks) from semantics (what is there).

This isn't the place to try to do a full CSS tutorial; this one is pretty good as a survey. What you'll be doing is adding a few more tags - <div> and <span> - to define specific chunks of your page and where to put them. It's a great tool and a way to distinguish yourself from just another CGI programmer.

CSS will take you the next step up from "okay, I got the data on the page" to "wow, that really looks good!". An inspirational example is the CSS Zen Garden; all the variant presentations are done via CSS using the same base page markup.
