Solid areas of screen real-estate

Leading on from the clearly differentiated top area, you'll notice that lots of sites define the various areas of real-estate boldly and clearly.

Real estate comes in various forms, including:

• Navigation
• Background / canvas
• Main content area
• Other stuff
• Callouts / cross-links

It's possible to design a web page so that these areas are immediately distinct from their neighbours.

The strongest way to do this is using colour.

But white space can be just as effective.

The risk with strong colour is that it draws the eye, so it can take attention away from other relevant screen elements.

I think that placing clean content on white space creates an easier experience, helping the viewer to feel more relaxed and free to browse.
