title: How to fill the background-color only for padding for Bootstrap's container-fluid?
body: <p>I try to fill only the padding of container-fluid with a background-color. 
  My container-fluid has a padding of <code>0 120px</code></p>
  
  <p>I found out that it should work like that</p>
  
  <p><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>.container-fluid {
    padding: 0 120px;
    background-clip: padding-box;
    background: grey;
  }
  
  .content {
    height: 1000px;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="container-fluid"&gt;
    &lt;div class="row content"&gt;
      &lt;div class="col-12"&gt;
        Content
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>but somehow this doesnt seem to work, what am I doing wrong?</p>
