title: How to fill entire div with background color
body: <p>I'm trying to get a background color to fill the entire div in a child div in bootstrap, but I'm completely stuck. I want the right section to be yellow, but it's only highlighting the text in the div. </p>
  
  <p>Here's a <a href="https://jsfiddle.net/hcgriggs/yjcrc91e/2/" rel="noreferrer">fiddle</a>.</p>
  
  <p>I know I'm missing something really obvious, but how do I get yellow to fill the entire <code>col-lg-6</code> div? 
  <div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.new-section {
    height: 100%;
    padding-top: 150px;
    text-align: center;
    background: #eee;
  }
  
  .yellow {
    background-color: yellow;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/&gt;
  
  &lt;section id="new" class="new-section"&gt;
    &lt;div class="container"&gt;
      &lt;div class="row"&gt;
        &lt;div class="col-lg-6"&gt;
          &lt;h1&gt;Section left&lt;/h1&gt;
        &lt;/div&gt;
        &lt;div class="col-lg-6 yellow"&gt;
          &lt;h1&gt;Section right&lt;/h1&gt;
        &lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/section&gt;</code></pre>
  </div>
  </div>
  </p>
