ok...lets clarify a few things and see if we can get you pointed in the direction you want.
The SAMISITE.COM home page is built in CSB using a simple page that has NO borders. I have set my page template in EDIT > PAGE LAYOUT to turn off all the borders. Right click the border than chose PROPERTIES > PAGE AREA and UNCHECK your box to show the border. (I actually made a NEW page layout for the home page and some other pages on my site that has no borders at all and left the standard CSB page layouts intact.)
With no borders on the page, the samisite.com home page looks like a plain white sheet of paper.
The background color is put into the PAGE PROPERTIES area. You can use a flat color or use an image, as I did, to define a general tone for the page. I used a green background with lines for the forum and the lavenderish version of the image used on the home page is here:
THEN I simply use a CENTERED TABLE to hold the stuff on the page!
That particular page, the table is fixed size and will not adjust.On other pages, I have set the table to EXPAND (% of screen).
In the big 3-column table, I have other tables....I control the colors or transparency of my tables, adjusting the border lines to show or not depending on the effect I want.
The centered table is often used to control the look of the page. And when you have images and text, the table does a nice job of holding the pieces of your site where YOU want them.
The BORDER you speak of really doesn't exist.
It is simply the background that will appear if the window is WIDER than the table being displayed. I built tables to fit 800x600 resolutions and on some larger resolutions the table looks tiny. Since I still use 800x600 at work, I want my site to look decent when I am looking at it on that monitor. I set my home monitor to 800x600 before I open CSB, then work in my design file. If it fits in that window, it will fit on 800x600 browser window without having a lower scroll bar.
