Centering a Website - Liquid

Hi,

I am building a website and would like to make it liquid. The website address is:

http://www.cse.dmu.ac.uk/~p04283218/mainframe9/

Can anyone point me in the right direction as to how I would do this please.

Thanks.

Make all your widths based on percentages is my advice if you are going for liquid.
