Hi

i get a D6 custom theme and i would to get it responsive.So i found AT that seem great but i can't understand the logical.
Usually responsives base themes use grid system or likelly,but here i don't find a piece of this stuff.
Actually i use a page-front.tpl and template suggestions for D6 ( ex: http://www.lycee-edmond-rostand.fr) and i would transpose this into an AT sub-theme,but how to adapt my layout ?

thanks
