main.css (correct order)

After analyzing the dojo.css file I understood, that my main.css file and the dojo.css are the files for generic css statements (just different settings).

The right solution: exclude the dojo.css file. Now I have the formatting from my main.css file and everything (except of the dojo TabContainer) is under my controll.
(See the font-size and the font-family on the images).

<link type="text/css" href="css/main.css" rel="stylesheet" />
<style type="text/css">
	/* @import "/dojo/dojo/resources/dojo.css"; */
	@import "/dojo/dijit/themes/tundra/tundra.css";
Tab 1 content
Tab 2 content
