Building a Successful Software Web Site

I spent all the day designing a template for the new site. I have a number of successful temlates but this one must make a difference. First of all, I need a CSS layout, not a tabled one. Separating structure from presentation is a standart now. Moreover, it gives some SEO advantages as CSS lets me move the most important contents to the top of the document. Also, it lets me get a good text to markup ratio.

Template requirements:

• Clear and consistent navigation.
  People expect to see the site menu on the left, so this is where it must be located. Also, I need additional navigation (Bread Crumbs). The site will contain a large number of articles. Bread Crumbs will help me show users where they are and how the information is structured.
• Color contrast.
  Black text on white background is easy on the eyes.
• Large Download Block above the fold.
  Do not make users scroll down in order to download the trial version of your software.
• Valid CSS and XHTML.
• Style sheet for printing.
