Heres a simple plugin that fixes the gallery so it validates by pushing the css into <code><head></code> and a couple of other little tweaks. 
Also fixes the comment form by removing the ‘aria’ bits that wont validate as XHTML.
Now with youtube and googlevideo fixes!

What The File adds an option to your toolbar showing what file and template parts are used to display the page you’re currently viewing.
You can click the file name to directly edit it through the theme editor, though I don’t recommend this for bigger changes.
What The File supports BuddyPress and Roots Theme based themes.
