When nesting grids use the
group class to eliminate gutters on the parent element of the columns that are being nested.
It provides a padding-less container for nested columns and subsequently, helps avoid the indentation and side-padding issues otherwise seen on nested columns with
lastUnit parent classes.
Wherever possible, limit nesting grids to 2 levels deep. Anything more than that would require the use of
nopadding on grid columns or
units for correct grid alignment and indentation.
