title: Make child div occupy 100% height
body: <p>I want to make the child div <code>.status</code> be at the <code>height</code> of <code>100%</code> the <code>.container</code>.</p>
  
  <p>The problem is that that I can't specify an exact <code>height</code> for the <code>.container</code> div, because it must have a dynamic <code>height</code>.</p>
  
  <p>Here is the <a href="https://jsfiddle.net/6L23dmpr/2/" rel="nofollow">JSFiddle</a></p>
  
  <p>Here is the 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>.container {
    width: 100%;
    background-color: red;
    float: left;
    box-sizing: border-box;
  }
  .progress {
    float: left;
    width: 5%;
    background-color: green;
    height: 100%;
    box-sizing: border-box;
    margin: 5px;
  }
  .content {
    float: left;
    width: 80%;
    background-color: #f2f2f2;
    height: 100%;
    box-sizing: border-box;
    margin: 5px;
  }
  .status {
    position: relative;
    float: left;
    width: 10%;
    background-color: #c2c2c2;
    height: 100%;
    box-sizing: border-box;
    margin: 5px;
  }
  .priority {
    position: relative;
    height: 20px;
    top: 5%;
    background-color: #a2a2a2;
  }
  .prog {
    position: absolute;
    width: 100%;
    height: 20px;
    bottom: 5px;
    background-color: #d2d2d2;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="container"&gt;
    &lt;div class="progress"&gt;
  
    &lt;/div&gt;
    &lt;div class="content"&gt;
      &lt;h2&gt;
     Some Content Text.... Some Content Text....Some Content Text....
     Some Content Text....Some Content Text....
   &lt;/h2&gt;
    &lt;/div&gt;
    &lt;div class="status"&gt;
      &lt;div class="priority"&gt;
      &lt;/div&gt;
      &lt;div class="prog"&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
