title: Horizontally scrollable div inside full width div
body: <p><a href="https://i.stack.imgur.com/Nt0e9.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Nt0e9.jpg" alt="enter image description here"></a>
  I have a division which horizontally fits the screen inside which I have 5 divisons, I want 4 divisions to appear on screen and 1 division to appear when I scroll the division horizontally. And I want the scrollbar to appear inside the div only and not on the browser window.</p>
  
  <p>Below is my non working code which puts the h1 tag in the left, I want it on the top-left then under it all 5 divs</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>.outer {
    overflow-x: scroll;
    width: 100%;
  }
  
  .inner {
    width: 25%;
    float: left;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="outer"&gt;
    &lt;h1&gt;Header Title&lt;/h1&gt;
    &lt;div class="inner"&gt;
    &lt;/div&gt;
    &lt;div class="inner"&gt;
    &lt;/div&gt;
    &lt;div class="inner"&gt;
    &lt;/div&gt;
    &lt;div class="inner"&gt;
    &lt;/div&gt;
    &lt;div class="inner"&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
