HTML is even worse about letting you have control over using different fonts. Essentially you have one font and a typewriter font. More than that, you have little/no control over what the main font actually is because your user can set this in her/his own Netscape (or other browser). so, you basically have no control. If you really want to have variation in font, you can make your text as an image (or raster file) in Photoshop and treat it as an image in HTML. The following is about all you can do (these are all at size 5):

I'm default
I'm in bold
I'm in italics
I'm in typewriter mode
I'm in 
	t y  p   e     writer 
	p
	 r
          e
            format mode


NOTE: Some browsers now support the font "face" option. This works like:

I'm in Helvetica.
I'm in Times.
I'm in Avant Garde.
I'm in NEW YORK.

There's a catch, though. The person looking at your page has to have that specific font installed on their machine. All they will see if they fon't have it installed is normal HTML text.
