You can and basically all pages should work this way.
Whether they are fluid, which means the expand and contract with the size of the window, or they are static, that is they have the same dimensions always regardless of screen resolution.
Specifying dimensions will keep the page static as it will always need to be as big as you specified. This of course means that space not used up by the websit in larger resolutions will be empty. either as bars to either side of the page, or a single bar on one side if the page is not centered.
If you want a website that grows or shrinks with the size of the window its in, and thus with the different screen resolutions, then fluid design where you use percentages, and take into account sections that may grow is what you want.
