People do not like to read lines of text that go all the way across the page. The fewer words you put on a line, the better. You can indent your text, but then you waste a lot of space on the left and right side of the page. A better alternative would be to create a two-column table. The column on the right is usually wider and contains the bulk of your text.
Fonts are tricky.
A browser will not display a font you have specified unless the user has that font installed on his or her system. You want to list a couple of fonts, because Mac users have one name and Windows users have another for the same font. Giving the browser a list of fonts to try will ensure that your page looks roughly the same on either platform. In my BODY tag, I used the color words silver and teal for my bgcolor and text. It's actually a trade off.
