title: Can't get the header above my flex items and centered inside the flex container
body: <p>I have three flex items aligned at the center on both axis inside a flex container. My problem is that the header of this section is also aligned with them. Instead it's supposed to be centered above them. I'm still learning.</p>
  <p>The Snippet:</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>.big-location-container {
    height: 500px;
    width: 1200px;
    margin: 0 auto;
    display: flex;
    justify-content: center;
    align-items: center;
    background-color: white;
  }
  
  .location-container {
    width: 300px;
    height: 50%;
    margin: 15px 40px;
    background-color: black;
    opacity: 1;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="big-location-container"&gt;
  
    &lt;h2&gt;Locations&lt;/h2&gt;
  
    &lt;div class="location-container"&gt;
      &lt;h3&gt;Downtown&lt;/h3&gt;
      &lt;p&gt;384 West 4th St&lt;/p&gt;
      &lt;p&gt;Suite 108&lt;/p&gt;
      &lt;p&gt;Portland, Maine&lt;/p&gt;
    &lt;/div&gt;
  
    &lt;div class="location-container"&gt;
      &lt;h3&gt;East Bayside&lt;/h3&gt;
      &lt;p&gt;3433 Phisherman's Avenue&lt;/p&gt;
      &lt;p&gt;(Northwest Corner)&lt;/p&gt;
      &lt;p&gt;Portland, Maine&lt;/p&gt;
    &lt;/div&gt;
  
    &lt;div class="location-container"&gt;
      &lt;h3&gt;Oakdale&lt;/h3&gt;
      &lt;p&gt;515 Crescent Avenue&lt;/p&gt;
      &lt;p&gt;Second Floor&lt;/p&gt;
      &lt;p&gt;Portland, Maine&lt;/p&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
