Preview pages in Snapshot
With Snapshot, you can see how your page renders in the browser of your choice, right inside Microsoft Expression Web. Just like with other panels, you can move it and dock it wherever you like.
You can preview ASP.NET, or PHP web pages by using Microsoft Expression Development Server. The Expression Development Server is installed when you install Expression Web. If you need to repair or reinstall Expression Development Server, see Installing Expression Development Server.
For information about using a custom URL for preview, see Preview pages in a browser.
When Always Preview Active Document is on, the Snapshot view updates every time you select the tab of an open page or open a new page.
