Microsoft Expression Web Designer 2007

Expression® Web® is a professional design tool to create modern, standards-based sites that deliver superior quality on the Web.

Create CSS-based, XHTML 1.0 Transitional-conforming Web sites by default. Work better across browsers, simplifying deployment and maintenance. Configure flexible schema settings to support all combinations of HTML, XHTML, Strict, Transitional, Frameset and CSS 1.0, 2.0, and 2.1 plus browser-specific schemas. Validate your site with compatibility and accessibility reporting and against Section 508 and W3C Content Accessibility Guidelines (WCAG).
