Buttons were originally intended for forms and stuff like that. Links built the web I suppose. "Hyper-Text" was the making of the WWW as we know it. Anyways...
<a href="page.htm" title="Page">Page</a>
a - defines a link
href - the location of the document (the URL)
title - the title/description of the link
- the only part that is visible; the text you click on to got to the page
