If you aren't using an html5 doctype and have something like...
<div id="box"><a href="page.html">Your link here</a></div>
But you want the link on the entire container, you could use css to turn an <a> tag into a block element so it acts like a <div> and then style accordingly...
<a id="box" href="page.html">Your link here</a> <!-- remove the <div> wrapping the <a> -->
The css could be something like...
a#box {
display:block;
height:20px;
width:100px;
font-size:10px;
line-height:20px;
text-decoration:none;
text-align:center;
color:white;
background-color:blue;
border:1px solid black;
}
This will create a little blue box with rounded edges surrounded by a 1 pixel black border with white text centered both horizontally and vertically. The entire box will act as the link.
