Hello dear skilled javascript developers,

I need your wisdom on a little thing here :-)

I have this page http://www.europasprak.com/engine/mo...isePageId=3804

And I wonder why the tabs: La nationalité des personnes célèbres Exercice Exercice 2
are appearing on the right (as seen on Firefox and Chrome) on not on the left as they should.

Any clue ?

Thank you !
