This would be so much more awesome if you could assign the class to a container div. Then on each page reload it would randomly add content - be it paragraphs, headers, imgs, lists, tables etc.

This would be a fantastic tool for testing templates against a wide variety of random content. When making a template for clients to use you can never be too sure what they are going to add so you do your best to style everything. Getting random content on each page load would really solidify this testing.

Adding a class to individual elements... I don't find this too useful.
