Found a rather nice site that has some examples of 1, 2 and 3 column web layouts using CSS The Layout Reservoir – BlueRobot
These seem to look a bit nicer than some other examples that I have seen
Edit:
I feel that I have made some “Improvements” to the left menu layout design… see Re-sizeable Two Columns – Left Menu CSS
Just my strange ramblings… don't worry they take up no more room than an elephant in a gin and tonic.
