Review of Anchor / Link Tags
A hyperlink or a link is a pointer from one page (or file) to another.
<A HREF="page.html">link text</A>
The A stands for anchor, the HREF means HyperText Reference

Link colors are part of the page properties. If you change them using the page properties dialog box (in Dreamweaver), you will be setting the color values for the ALL the links on that page.

Another approach (and what we looked at in yesterday's class), is to use CSS or style sheets to define your anchor or link tags.
A:link
A:visited
A:active
A:hover
