I am reading (an thoroughly enjoying) the book "More Eric Meyer on CSS". But there is one thing he keeps doing which seems backward from any other book or tutorial.

When he styles a link, for example, to take away the underline, he does this:

a {text-decoration:none;}

Every other resource i've read says to do this:

a:link {text-decoration:none;}

Is there a difference?

To add to my confusion, in this book, on p. 106, he does something like this:

a {text-decoration:none;}

This is the first time i've seen him use a:link. His other book never used a:link. Here he is using it along w/ "a".

Can someone please help clarify what's going on here?

Thanks so much!
