Often times I end up creating short pages for testing short pieces of code, and I only need a very basic HTML template to write in. Short of using HTML5 Boilerplate, I just use a quick piece of code like the following. (note: yes, this has issues in IE, so you may want to use HTML5 Shiv/Shim)
Edit: Self-closed tags for compatibility.
