<STYLE type="text/css"> body {font-family:sans-serif;font-size:12pt;}</STYLE>

Can also be used as an inline element. Example:

<UL style="font-size:15pt">

<LINK>

Is used to reference a document's style sheet from a .css document that contains only style sheet elements. Example:

<link rel="stylesheet" href="reference2.css" type="text/css">

CLASS

Is used to assign a particular style to a certain element inside the body of a document. Example:

H4.BOLD {font-weight:bold; }

ID

Is used to individually name a style. Thus you could specify, within an element, a class and an id. Example: H4.BOLD {font-weight:bold;} #myfont {font-family:verdana;}

<SPAN>   </SPAN>

Is used to apply style sheet elements to specific text. Example:

<SPAN style="color:#CC0000;font-weight:800;font-style:italic">This text is bold, red, and italic.</SPAN>

/*COMMENT */

Comments for style sheets help guide a programer inside the coding his style sheet, which can not be viewed from the surfer side of a browser.
Example:

P {font-size:12pt; font-family:verdana, Arial; }
/* Use multiply fonts but leave Arial last as default */
