title: Footer refuses to stick at the bottom
body: <p>I have just recently got into coding, hence the messy code and css (<a href="http://codepen.io/valik140795/pen/zBgXRg" rel="nofollow">http://codepen.io/valik140795/pen/zBgXRg</a>) . I am currently struggling to position my footer underneath the second grey box with 5 images (instead of being next to it). I have tried countless posts from this website and other sources with no luck. Please help. Thank you in advance.</p>
  
  <pre><code>      .block_footer {
      position: fixed;
      width: 100;
      margin: 0 auto;
      height: 200;
  }
  </code></pre>
