How do I make a particular cursor for a link?

[Apprehender]

I just need some help as I am working on my blog, and want to make it look as good as my friend's ones, so, is there such a thing as setting the particular 'rollover' cursor for the whole webpage? Please advise.

for a simple one, you could paste this into the head and change the colors accordingly

<STYLE TYPE="text/css">
a:link { color: blue; text-decoration: none }
a:active { color: red; text-decoration: none }
a:visited { color: blue; text-decoration: none }
a:hover { color: green; text-decoration: underline }
</STYLE>
