As a programming student, I've been trying to acquaint myself with Dojo for a javascript project. In my jsfiddle here: http://jsfiddle.net/brennonbrimhall/BdpFm/3/, I've copied several other examples of dijit widgets, but I've been unable to resolve the tabs. It seems to me that it's only rendering halfway, as compared to the examples here: http://dojotoolkit.org/reference-guide/1.8/dijit/layout/TabContainer.html
Are there any obvious mistakes I'm making?
