Some common answers

What's going on with my TITLE and TEXTAREA?

Those two tags are different. You can close them ONLY with a closing tag.
For example, the following snippet:
<html><head><title /></head><body>hello world!</body></html>
has the 3 tags only: html, body, and title. The text for title tag is everything from the </head up to the end of the string.
