I have to agree with kxcntry99. Using Table Layouts, although seems easy at first, where as CSS can be a little bit daunting, can cause you problems down the line.

Too many nested tables makes markup difficult to maintain, and slow to render.

A great place to start with getting to grips with CSS is here:

And for general tutorials, have a look here:

and here:

and not forgetting here:

CSS can be scary to start with, and you will run into problems getting it to look the way you want it, but stick with it, and post back any questions that you might have.
