how do you make a fixed style fit to screen?

im working on a style for my site, and before i get any further, how do i make it be the size of the users screen settings?

You would need to make it a percentage width rather than a fixed pixel width. For example, you can have styles that are 100% or 95% or whatever you want, and they will cover that much of the screen regardless of screen resolution.
