title: HTML Div is not full height when overflow occurs
body: <p>I have a problem. I created the following simplecode:</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>* {
      box-sizing: border-box;
      margin: 0;
      padding: 0;
  }
  
  html, body {
      height:100%;
      min-height:100%;
  }
  
  
  .page-content {
      width: 100%;
      border-radius: 10px;
      margin: 10px auto auto;
      padding: 5px;
      height: 100%;
      background-color: blue;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;html lang="en"&gt;
  &lt;head&gt;
      &lt;meta charset="utf-8"&gt;
      &lt;title&gt;EWA&lt;/title&gt;
      &lt;base href="/"&gt;
      &lt;meta name="viewport" content="width=device-width, initial-scale=1"&gt;
      &lt;link rel="icon" type="image/x-icon" href="favicon.ico"&gt;
      &lt;link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.7.1/css/all.css"&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;div class="page-content"&gt;
      &lt;div style="background-color: red; width: 400px; height: 2500px;"&gt;&lt;/div&gt;
  &lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;</code></pre>
  </div>
  </div>
  </p>
  <p>As you can see the class <code>.page-content</code> has a height of 100%, but the div inside the <code>page-content</code> overlaps it. Why does the <code>.page-content</code> not go to the bottom of the page?</p>
