title: What is the most reliable clearfix method for HTML in emails?
body: <p><code>clear</code> doesn't work in Outlook 2007/2010, as well as <code>display</code> (and many other CSS properties). What should I use?</p>
  
  <p>I need to support all of the clients in <a href="http://www.campaignmonitor.com/css/" rel="nofollow">this matrix</a>, except Lotus Notes.</p>
  
  <p>FYI: I am using an XSL that is building <strong>all grid-based markup with tables</strong>. However, I have a table unit that is overlapping another (only in Outlook 2007/2010) somehow.</p>
