title: How to make the height of the div take all the space?
body: <p>Here is my css rule together with the markup:</p>
  
  <pre><code>&lt;div style = "height:100%;"&gt;
  &lt;div style = "width:220px; margin-left: 200px;font-size:16px; height:auto;"&gt;
      &lt;div class='navbar-inner'&gt;
          &lt;div class='container'&gt;
          &lt;ul class="nav nav-list"&gt;
              &lt;div&gt;   
              &lt;li &lt;?php if($page == 'upload_track'){ echo "class = \"active\""; }?&gt;&gt;&lt;a href = "#"&gt;Upload a new Track&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href = "#"&gt;View all blog post&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href = "#"&gt;View all tracks uploaded&lt;/a&gt;&lt;/li&gt;
          &lt;/div&gt;
          &lt;/ul&gt;
      &lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  &lt;div style = "width:220px; margin-left: 200px;font-size:16px; height:auto;"&gt;
  </code></pre>
  
  <p>as of now I am making them an inline style so that it would be easy for me to change them. since switching texteditors is kind of a hassle for me.</p>
  
  <p>How would I make that div take up all the available height? like the very bottom of the page. as of now it looks something like this

  <p>what I wanted to see is that the black div takes up all the available height in the page</p>
