Need a code...

Which will make my layout fit to screen of any screen resolution.
I'll be using iFrames too.

THanks & +rep to anyone who helps. :)

Instead of using set width
IE/ 200px, 400px, 600px
Use Percentages.
IE/ 20%, 50%, 75%

Also if your using something thats is contained in a table/Div (EG. Iframe) put the width as 100%
