title: Get window height?
body: <p>window height is getting the length of the html document rather than the size of my browser window.</p>
  
  <p>Do you know where I'm going wrong?</p>
  
  <p>Here's my script:</p>
  
  <pre><code>$(document).ready(function() {
              alert($( window ).height());
      });
  </code></pre>
  
  <p>I also have at the top of my doc which I've read can cause issues:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  </code></pre>
