Immediately after visiting the Tripoli sample page (http://devkick.com/lab/tripoli/sample.php), I was going to applaud the team for not making the dick move that usually takes the form:

  body { font-size: 0.65 em; }

Then I realized the stylesheet wasn't enabled. tripoli.simple.css:

  html{font-size:125%}body{font-size:50%}

Bummer.
