Just started playing around with bootstrap 3 and I can't get gutters between columns to work.

I created the most basic code to test with:

<!DOCTYPE html>
<html lang="en">
<head>
    <title>Test</title>
    <script src="http://code.jquery.com/jquery.js"></script>
    <script src="//netdna.bootstrapcdn.com/bootstrap/3.0.0-rc1/js/bootstrap.min.js">                                                                                                                                  </script>
    <link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0-rc1/css/bootstrap.min.css" rel="stylesheet" media="screen" />
    <style>
        .box1 {
            background-color: green;
        }
        .box2 {
            background-color: blue;
        }
    </style>
</head>
<div class="container">
    <div class="row">
        <div class="col-lg-4 box1">
            <h1>Test</h1>
        </div>
        <div class="col-lg-8 box2">
            <h1>Test2</h1>
        </div>
    </div>
</div>
</html>

And the result is just one big green/blue box without any gutter in between the two columns. I have also tried it on a fiddle with no luck http://jsfiddle.net/Tgkkb/ What am I missing?
