Btw. I recomend using div tags for layout and tables just for tabular data.

It is however, considered by some, to be very bad form to use tables for layout. I am redsigning using css.
I was confused at first with css. Mostly because css styles can be used on a page but also called from an external style sheet. For me, the important first step was understanding the seperation. Next, the layout is done on the page with div tags, blocks, etc, each being given a name such as 'div header', 'div footer'. The style sheet contains the style info for each of these named layout areas, aswell as styling for tables text, in fact everything on the page.
I suggest setting aside 2 or 3 days and following a tutorial on css. Not just reading it but actually doing it. Include in your research a complete view of css at w3schools. Once you've grasped the idea and realised what you can do with css, it is only necessary to decide exactly what you want on your page. Building the style sheet is then a swift process. Providing you set a style for everything on the page it doesn't really matter what styles you apply initially because they're so easy to change. I'll try and find the link to the tutorial I used and post it later.
