am trying to put a divider line that runs across my web page from left to right. The line would go under my logo (Conrad's Computer Solutions) and above the text (where it says welcome to my first site). I am using CSS for my pages. Is there a way to put this divider line there using CSS? I will paste a copy of my CSS code and the code for my the index page on my website. Please tell me where I am going wrong, this is driving me nuts!!!

CSS code :

body
{color : 000000;
background-color:#FFFFCC;
margin-top: 230px;
margin-bottom: 60px;
margin-left: 40px;
margin-right: 40px;
background-image : url('logo3.gif');
background-position : 50% 25px;
background-repeat : no-repeat;}



Index page code (HTML):
