How to make a div extend the full screen

I've tried to make it work many ways for the last couple of hours but haven't been able to make it work through all browsers correctly. What I'm trying to do is extend a container div background all the way to the bottom of the page, even if there's not enough content.

<html>
  <head>
  </head>

  <body>
    <div class="container">
      <div class="content">
        <p>blah blah blah</p>
      </div>
    </div>
  </body>

</html>

html,
body,
.container {
  height: 100%;
  margin: 0;
}
body {
  background: steelblue;
}
.container {
  background: gray;
  margin-bottom: 2em;
}

Hello James.

I was just wondering why the browser adds an extra space above the .container div, and how to remove it.

I was experimenting with the code and I could remove it by:

  • setting the margin-top to 0 on the p element
  • setting the width property of .container to 100% and its position to absolute

However, I would like to fully understand this problem.

I hope you can reply. Thanks.

The issue is that there's no content above your <p> so it's margin pushes it down, you're right about <p> tags do having margin removing the top margin in cases like this solves the issue.
