title: Close the curent tab - IE
body: <p>I want to close the current tab.</p>
  
  <p>This is what I've got so far.</p>
  
  <pre><code>&lt;a href="javascript:window.open('','_self').close();"&gt;Close Me&lt;/a&gt;
  </code></pre>
  
  <p>It displays a link. But I want to a button. How to use it in a button?</p>
