title: CSS 3 - transition prefixes - which ones to use?
body: <p>I have a question regarding the CSS vendor prefixes for transition.</p>
  
  <p><a href="http://html5please.com/#transition">This source</a> states that "you need to use all the usual prefixes to make this work in all browsers (-o-, -webkit-, -moz-, -ms-)".</p>
  
  <p><a href="http://www.css3files.com/transition/">That page</a> only shows the <code>-webkit-</code> and <code>-moz-</code> prefixes and claims that IE 10+, FF 16+ and Opera 12.1+ can read the prefix free version.</p>
  
  <p>In the code of Twitter Bootstrap, there is always exists a <code>-webkit-</code>, <code>-moz-</code> and <code>-o-</code> prefixed version in addition to the un-prefixed version.</p>
  
  <p>What prefixes should I use?  </p>
