Configuration

Global settings (and default values):

@gs {
  width:   20.5rem;  /* width of a single column */
  gutter:  1.5rem;   /* width of the gutter */
  padding: 1.5rem;   /* padding of the main container */
  max:     8;        /* maximum number of blocs (wide screens) */
  min:     2;        /* minimum number of blocs (mobile) */
  align:   center;   /* center or left */ 
  display: flex;     /* float or flex */  
}

A breakpoint is created for each value from min to max. When the screen is narrower than min * width, elements are fluids.
