Well you can design it small, like 640x480, and center it in the page. Or, just set your monitor to 800x600 resolution and see what your page looks like.
I am designing pages on a 17in monitor but expect it to be viewed on 15in monitors at some point. I hate scrollbars appearing on my pages. Has anybody got any tips short of running a 15in monitor along side my 17?
I am using Dreamweaver with tables set to 75% wide.
