1) Always be certain that your page passes the HTML validator at http://validator.w3.org/.
2) If you want that to look a little better, use CSS (http://www.w3.org/TR/REC-CSS2/).
3) That's a bit more robust than you'll need for your homework. See http://devedge.netscape.com/library/manuals/2000/javascript/1.3/guide/regexp.html for how to adjust the pattern matching.
