title: Issues with making a div and header in a div the same height
body: <p>I have an issue. I want the <code>div</code> with the image to have the same height (scaling when you resize the window). Could anyone help me out here? I don't get why the <code>height: 100%;</code> doesn't make it's size as big as the parent <code>div</code>.</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: darkred;
    color: #bfbfbf;
    font-family: Roboto, serif;
  }
  
  .image {
    float: left;
    width: 30%;
    margin: 0 .5% .5% 0;
    border: 1px solid white;
    box-sizing: border-box;
  }
  
  div.head:after {
    content: "";
    display: table;
    clear: both;
  }
  
  header {
    float: right;
    width: 69%;
    height: 100%;
    background-color: black;
    border: 1px solid white;
    box-sizing: border-box;
  }
  
  .image img {
    width: 100%;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="head"&gt;
    &lt;div class="image"&gt;
      &lt;img src="../assets/Triumph_Spitfire.jpg" alt=""&gt;
    &lt;/div&gt;
    &lt;header&gt;
      &lt;h1&gt;Triump Spitfire&lt;/h1&gt;
      &lt;hr&gt;
      &lt;p&gt;“poor man’s Jaguar E-type”&lt;/p&gt;
    &lt;/header&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
