Page Inspector is a new tool that brings browser diagnostics tools into Visual Studio and provides an integrated experience between the browser, ASP.NET, and source code.
Page Inspector enables you to easily quickly diagnose issues. Using Page Inspector, you can see what elements in the source files (including server-side code) have produced the HTML markup that is rendered to the browser.
Page Inspector also let you modify CSS properties and DOM element attributes and see the changes reflected immediately in the browser.
