Microsoft Expression Web 3.0 Software
Expression Web speeds the essential task of cross-browser debugging. With SuperPreview, you don't need a Web service to debug your pages on the same machine that you use for development. SuperPreview not only shows a high-fidelity rendering of how pages will look on different browsers, but it also identifies the element's tag, size and position, applied styles, and location in the DOM (Document Object Model) tree so you can quickly fix the error.
