Hi,
in the provided themes, and when compiling, and for each less files section... the order of loading less variables from media directory after from the theme it self is not good i think...
because themes variables are then overriden by default media dir variables...
see example :
components\com_easysocial\themes\wireframe\styles\groups.less
media\com_easysocial\styles\config.less
media\foundry\4.0\styles\bootstrap3\variables.less
==> components\com_easysocial\themes\wireframe\styles\variables.less
==> media\com_easysocial\styles\variables.less
media\foundry\4.0\styles\foundry\mixins.less
media\foundry\4.0\styles\bootstrap3\mixins.less
media\com_easysocial\styles\arrow.less
components\com_easysocial\themes\wireframe\styles\groups\listing.less
thanks
