If you want to “view source” for an HTML page on the Nexus 7, you can do so in Chrome by prepending “view-source:” to the URL. Example:

view-source:https://alexking.org

This will also work (it redirects to the http:// verision):

view-source:alexking.org

This also works in the desktop versions of Chrome and Firefox, but doesn’t seem to work in Safari (desktop or iOS) or Chrome for iOS.
