Some test HTML for Drupal themes
It’s all too common that you hand a Drupal site off to a client, only to realize that the WYSIWYG threw in a common element (such as a blockquote perhaps) that should work look beautiful, but it looks like crap because you never tested it.
As an attempt to solve that, I gathered a crap-ton of markup to be used to test your Drupal theme. It includes both regular HTML elements (pretty much every one you can think of), as well as Drupal-specific stuff (such as tabs and status messages). The purpose of this markup is that you can copy and paste into a node and you have your very own markup tester.
Even though it’s just a single file, I went ahead and put it on GitHub with my other pet projects.
