You have to replace < with &lt; to make the code show up on the MB without being parsed, even if you put it in code tags.  Blah.  *kicks the VB*
In CSS, there are different ways to specify what a style affects.  A word by itself = just a tag.  So  would affect all a-tags.  A word starting with a period, as in .Mint, indicates a class.  So 
	Code:
	.blahrg {color:#f00}
  in the stylesheet would affect any tag with class="blahrg".  (I don't know why everyone is using the word Mint.  You can use any word for a class.)  A word starting with a # indicates an id, so  would affect any tag with an id="main".  
You can also combine them.  When one word follows another word, it means "Any of the second which is a child of the first".  So 
	Code:
	a .menu {border:0px}
  would affect any tag which has class="menu", which is INSIDE an a-tag. So 
	Code:
	<a href="blah"><img src="blah.jpg" class="menu"></a>
  would make that img tag have a property of border:0px;
On the other hand, something like a.class means "an a-tag, with a class 'class'".  That's probably what you want.  So 
	Code:
	a.blahg { color: #f00}
  affects all a-tags which have a class="blahg".  Like 
	Code:
	<a href="test" class="blahg">test</a>
 There are a great many rules, and I'm not sure I can go into them all.  So yeah, try something like this.
	Code:
	<style type="text/css">
a.blahg {
   color: #f00;
}
a.arf {
   color: #00f;
}
</style>
 Then
	Code:
	<a href="test1" class="blahg">link1</a>
<a href="test2" class="arf>link2</a>
 Then the first link should be red and the second one should be blue.
