By setting a few parameters in the Template Manager Edit screen you changed the width and colors of the site template. Choosing a fixed width means the size of the layout will be the same, no matter how big the users' monitor or browser window may be. A fixed width of 900+ pixels is very popular these days and is used by big sites such as www.apple.com and www.microsoft.com. It looks good on most screens and leaves some room for left-hand side and right-hand side margins. Having a fixed width gives you pixel perfect control over the size of the layout; you won't have to bother adjusting our layout or graphics for different screen sizes (such as the fixed width header graphic we're going to replace in a minute).

The rhuk_milkyway template lets you change the colors and the overall width of the layout. There are other templates available with their own set of parameters that allow you to choose the number of columns or set other layout options.
