Well for starters you are using code specific to a site I did a while back, so unless you have the same structure i.e. ID's, classes etc it isn't going to work for you. Those samples I gave you were just samples. You need to modify them to your needs.
i.e. if your link to your
css file is foo.
css then you need a file called foo.
css in the location specified. Also if you want an element not to print in print.
css you need to specify that element in print.
css i.e. ul, ul li a {display:none;} or whatever.
For Example:
a:link, a:visited, a:hover {
color: #000;
text-decoration: underline;
}
The above will make every link black and underlined regardless of its state.
