Hello all, I am facing a problem and I do not know what to do. The CSS styles I define as classes are not showing up on my browser previews, however, in DreamWeaver they look fine, I have ruled out any human error, I really don't think it's me, is there something I'm missing here?
This is the Style code that I placed in the HEAD
<style type="text/css">

.960px {
	width: 960px;
	margin: 0 auto 0 auto;

.2col { 
	width: 460px;
	margin: 0 10px 0 10px;

and these are the divs (they are in the body):
	<div class="960px">
		<div class="2col"> hi </div>
		<div class="2col">hello </div>
I have no idea what might be happening! It all seems fine, am I missing a dot somewhere?

Thank you in advance for your help,
I really appreciate it
