title: How can I test my webpage using different browsers?
body: <p>I just found out about the Yahoo UI <a href="http://developer.yahoo.com/yui/reset/" rel="noreferrer">Reset CSS</a> tool/file and I'm using it on my website. 
  On my machine I have Internet Explorer 7 and Firefox 3.01 and my webpage looks the same on these two browsers.  A friend is using Internet Explorer 6 and the page is completely a mess.
  I have two questions:</p>
  
  <ol>
  <li>Am I that poor/stupid in writing CSS?</li>
  <li>How can I test my webpage using different browsers on my machine?</li>
  </ol>
