title: What is the scope of the * CSS hack?
body: <p>I have been looking at a hack to solve a CSS problem I have. I haved used one to create a custom rule for Internet Explorer.</p>
  
  <pre><code>margin-top:45px;
  *margin-top:0px;
  </code></pre>
  
  <p>Does this hack apply to all IE browsers? Does this hack appear in any versions of Firefox or Safari?</p>
