Thanks for the answer !
I tried and :
- On the mobile phone, it's looks like every module are bellow each others. It's not possible to have the website but in full screen ? and i think it's still a module version, because when i look at the website logo, it's not the same at all of the PC version.
- On PC i had every modules bellow each others too, so i removed the comment of the 2nd line you told me
<!-- <link rel="stylesheet" href="<?php echo $yt->templateurl().'css/yt-bootstrap-responsive.css';?>" type="text/css" />-->
And now it re-work on PC.
But it's still weird on phone.
