title: Container's height doesn't occupy the whole webpage
body: <p>I want the container's height (with white background) to occupy the whole webpage, it was doing that. </p>
  
  <p>I've forked my webpage and tried to replicate the bug, by commenting out and testing the code part by part. I'm fairly certain that when I used dl dd dt tags, it kinda broke the website. However, sometimes those tags break the design sometimes they doesn't. Can anyone take a look at the code, and explain to me what's going on and how to resolve it? Thanks.</p>
  
  <p><strong>HTML</strong></p>
  
  <pre><code>  &lt;div class="pad-left pad-top"&gt;
      &lt;h2 class="title"&gt;Timeline&lt;/h2&gt;
      &lt;dl&gt;
        &lt;dt&gt;June 28, 1971&lt;/dt&gt;
        &lt;dd&gt;Elon Reeve Musk was born in Pretoria, Transvaal, South Africa, the son of Maye Musk and Errol Musk.&lt;/dd&gt;
        .....
      &lt;/dl&gt;

    float: left;
    width: 15%;
    /* adjust the width; make sure the total of both is 100% */
  }
  
  dd {

    width: 85%;
    padding-right:15px;
    /* adjust the width; make sure the total of both is 100% */

  <p><strong>EDIT:</strong></p>
  
  <p>Problem solved. I changed the margin of footer from the default 16px to 0px, and ta-da it worked. I suppose the margin of the website's last element (be it footer or whatsoever) will affect it, so I have to take note.</p>
