I actually have two website that contain the same content.
www.variablehtml.com is a fluid design site using nested tables
www.variablestyle.com is a series of fixed designs using CSS positioning.
The sites demonstrate how the page templates / designs can be altered as the browser width is changed.
The variable style site also changes templates as the font size (under the main navigation) is modified.
Most of the design is there to demonstrate the concept, not to represent the ultimate in web design. After all, who would want to break up the flow of text into two parallel columns where you have to scroll up and down to read the content?
The JavaScript merely chooses a different CSS file based on the browser width, plus the requested size on the variable style site.
The parallel sites were created with MySSI and the links at the bottom of each page are there to switch you between the fluid and fixed width designs.
Any comments would be appreciated.
