title: Set link height to 100% of it's parent
body: <p>If I have division with <code>height: 100px;</code> and it contains a link inside - can I make link fill the height of the division without hard-coding the value?</p>
  
  <p><code>&lt;div&gt;&lt;a href="#"&gt;hello&lt;/a&gt;&lt;/div&gt;</code></p>
  
  <pre><code>div {
      height: 100px;
      width: 100px;
      background: red;
  }
  
  a {
      background: green;
      height: 100%; /* This does not work. Is it possible to set this height to 100% of container? */
  }
  </code></pre>
