Cascading Stype Sheet Form 

CSS FORM [Placed between <head></head>  comments are used to block information for browsers that don't read style sheets. ] 
<STYLE  TYPE="text/css">
<!--
 rule1;
 rule2;
 rule3;
 ..... 
--> 
</style>

RULE
Selector(s) { Declaration(s) }
{ Property: Value ;}
H1, H2 { color: green ; 
background: red ; }

Selectors can be grouped,
Declarations can be grouped.

This example sets up the html href links:
<STYLE  TYPE="text/css"> 
<!--
A:link {color:#000000; text-decoration:none}
A:visited {color:#000000; text-decoration:none}
A:hover {color:#000000; text-decoration:underline}
A:active {color:#000000; text-decoration:none}
-->
</style> 
Note:  Active must be after hover to work.

Could also be:
<STYLE  TYPE="text/css"> 
<!--
A:link, A:visited {color:#000000; text-decoration:none}
A:hover {color:#000000; text-decoration:underline}
A:active {color:#000000; text-decoration:none}

-->
</style>
Note:  Can't include A:active on first line since it has to be after hover to work.



HTML Link to css file:  [where REL means relative, HREF means external html reference (could be HREF=/sheet1.css as well), TITLE is not normally used.]

<LINK REL="stylesheet" TYPE="text/css" HREF="sheet1.css" TITLE="Default">
