  <p>I already have the boxes but I don't know how to add a 2 color background. I'm using bootstrap.</p>
  
  <p>This is my code so far</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>body {
    background-color: #F9F9F9;
  }
  
  #container {
    margin: auto;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" /&gt;
  
  &lt;div class="container"&gt;
    &lt;div class="row"&gt;
      &lt;div class="col-md-12"&gt;
        BOX 1
      &lt;/div&gt;
    &lt;/div&gt;
  
    &lt;div class="row"&gt;
      &lt;div class="col-sm-4 col-md-6" style="margin-bottom:20px"&gt;
        BOX 2
      &lt;/div&gt;
    &lt;/div&gt;
  
    &lt;div clas="row"&gt;
      &lt;div class="col-sm-4 col-md-6" style="margin-bottom:20px"&gt;
        BOX 3
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
