Microsoft Expression Web provides new tools to make sure that the pages in your site work in multiple browsers.
Using SuperPreview, you can preview and compare pages simultaneously in multiple browsers, even in multiple versions of Internet Explorer. You can also compare browser views against a comprehensive mock-up ("comp") image.
You can select individual elements within a page and see details about each selected element, helping you quickly find and fix cross-browser layout and positioning errors.
For more information, see Displaying pages in SuperPreview.
You can add both Microsoft Silverlight and Seadragon Ajax Deep Zoom Composer images to your page in Expression Web from a composition created in Deep Zoom Composer.
For more information, see Adding Deep Zoom images.
Silverlight is a cross-browser, cross–platform plug-in for delivering rich interactive applications for the web. With Expression Web, you can add Silverlight applications to your web pages.
Expression Encoder Express is now included in Expression Web. You can use it to convert your video to Silverlight and add it to your page. You can even choose a "skin" to customize how the video player appears on your site.
For more information, see Add Silverlight video to a page.
