How to tell what font is on a webpage?

Actually quite easy. In Chrome, right-click, "Inspect," click "Computed" and click "show all." Then, scroll down to "font-family."

http://fontface.ninja - easy to use browser extension - enable it and hover the text you want to see the font of.

In general it is not possible, because your system can replace the font face specified by CSS with something else, and the browser doesn't know. For example, what font is used for "font-family: serif"? Fontface Ninja doesn't know.

In these cases you can sample the font and analyze it with something like WhatTheFont! or Font Matcherator.

Is there a way beyond combing through and parsing endless CSS files?
