Note that I did leave the </font> off of all except the first size in the display versions. You really should have an "end" for each tag, or at least end them all with </font></font></font></font></font> ... at the end of the last font change. If you don't close each one and reopen a new one with each change, as you go, it's easy to lose track of how many times to end end end them.

There are also a couple of other standard ways of getting different text sizes with a "Title1" "Titel2" or "Header1" etc, but I find the simple numbers sufficient. The problem is that the page header may set an unusual size, so you sort of need to preview to see how big a particular number will look relative to the rest of the page.
