Need Help with Site layout and screen sizes

Hi, so I built a site that looks good under my screen resolution though when I lower the screen resolution, which I believe is more the average screen size things on the page start getting scrunched up and pushed around. I built it in dreamweaver using only percentages to define where layers were horizontally I used pixel sizes for the vertical heights. I have heard something about me using absolute position in the CSS or something but I am not sure and am just looking for some help or guidance. The website is TextWick. Don't mind the green ad banner at the top, it's from godaddy since I haven't paid for the space yet.
Thanks a lot.

I have heard something else about using tables to build the site.

 

use should use one css file to put the stuff in. for ex. textwick.css

css part:

.header {
background: #FFF;
font: normal 1.2em "Trebuchet MS";
margin: 0 auto;
height: 200px;
(etc. etc whatever u want to specify in header section)
and close it with }

and the html part:

<div class="header">
TEXT TEXT TEXT TEXT
</div>

i´m not sure if i explain it quite good...but use one css file to put the stuff in.

 

If CSS isn't for you.. you can fix the problem with HTML tables by setting the width to %100 (that will fill the whole width of any screen resolution)
