This is really crazy, but I'm finding it impossible to center text in an html view.

This is not working:

<div style="text-align:center;">Please Center Me</div>

Nor is this:

<div align="center">Please Center Me</div>

Also not this:

<center>Please Center Me</center>

In all cases, the preview AND iframe views all push the text to the left:

Is it broke?

Or am I just being really dumb?
