title: What is behavior: url(); property in css?
body: <p>I was surfing and saw this css property which I have never seen or used before. I think it is related to Internet Explorer, and the structure is something like this:</p>
  
  <pre><code>#element{
    behavior: url(something.htc);
  }
  </code></pre>
  
  <p>What does the <code>behavior</code> property do? How would I use this property?</p>
  
  <p>I did find this <a href="http://www.w3.org/TR/1999/WD-becss-19990804#behavior" rel="noreferrer">w3 Documentation</a>, but it's not particularly clear what it does.</p>
