title: How to have a URL With a Query String and Focuses on Element?
body: <p>In the URL, you can focus on a particular element by appending a '#' and its id. For example:</p>
  
  <pre><code>http://stackoverflow.com?#footer
  </code></pre>
  
  <p>The code above will auto-focus you to the element with the id "footer".
  Now what if I would like to include a query string along with it? Like this:</p>
  
  <pre><code>http://stackoverflow.com?#footer&amp;id=3
  http://stackoverflow.com?&amp;id=3#footer
  http://stackoverflow.com?#footer+id=3
  http://stackoverflow.com/#footer?id=3
  </code></pre>
  
  <p>None of those URLs above seem to work. What's the correct URL?</p>
