Here is the solution to my problem.
In the CSS template i use, the H2 tag has some "special effects" on it (javascript, ajax or else, we don't care, that's not the point).
And that makes a big deal about its uses between the classes of the template of joomla and the code of CB...
Here is the workaround :
- change the H2 tag from the CB code to another tag (best)
- change (or disable) the H2 tag from the joomla's template to another tag (but if in the site, H2 is used, it won't be treated by the CSS correctly).

I'M HAPPY !!! I've calmed down the CSS
and by the way, i can display correctly that f**** CB
hihihi
