About Expression Web
Microsoft Expression Web is a full-featured professional tool for designing, developing, and publishing compelling, feature-rich sites that conform to web standards. Web designers, web developers, and visual design professionals can use Expression Web to create and produce sites.
Expression Web supports ASP.NET, PHP, Microsoft Silverlight, Deep Zoom Composer images, AJAX, and Silverlight video. You can import Adobe Photoshop files easily and publish your sites quickly and securely with multiple files transfer streams and secure FTP.
The multiple preview modes in Expression Web speed up your site development.

Use SuperPreview to compare your pages in multiple browsers simultaneously. You can even overlay pages from two different browsers to troubleshoot layout and positioning errors.
