Is there a way for the logo to be responsive in this template ?
I add the data-mobile=span6 at the xml of the layout
and also add #yt_logoposition .logo img {width: 100%;} at the css I use, but it's not working
thanks in advance

Ok, i found a solution

I delete the logo position from the layout, and change the social to span6
I make a custom html module, with the logo and insert it in social.
Finally make a responsive class and add it to the image in the module
