Blog Post Navigation Widget

I went ahead and tweaked out my sidebar navigation code to provide similar functionality for blog posts.

Here's the code:

<!-- BlogPostNav Widget By Benfinnigan.com /-->
<style type="text/css">
.postnavbutton {
cursor: pointer;
cursor: hand;
margin: 1px;
padding: 2px;
background-color: #ffffff;
color: #000000;
border-style: solid;
border-width: 1px 2px 2px 1px;
border-color: #C0C0C0 #000000 #000000 #C0C0C0;
}
.postnavbutton:hover
{
cursor: pointer;
cursor: hand;
margin: 1px;
padding: 2px;
background-color: #dddddd;
color: #000000;
border-style: solid;
border-width: 2px 1px 1px 2px;
border-color: #000000 #C0C0C0 #C0C0C0 #000000;
}
</style>
<script src="http://benfinnigan.com/js/blogpostnav.js" type="text/javascript"></script>
