Cascade Style Sheets
   - This is the link to the style sheet from this page:   
       <link href="../style4430.css" rel="stylesheet" type="text/css">
 
   - The style sheet itself, just has the stuff that would have gone 
       inside the style tag.  E.g. H1 {color: red}
 
   - You can also make sub types. E.g.  Div.lecture {font-size: 18pt}
   
 
   - You can then refer to them by adding the class argument: 
   <DIV class="lecture">
   
 
   - The point of CSSs is to make the whole site look the similar.
 
   - You can also have multiple sheets so that you can get hierarchical
       similarity.
