## Block Grids
-To define cell widths within a direction-level, instead of the individual cell level, add the class `.[size]-up-[n]` to a `grid-x` or `grid-y`, where `[n]` is the number of cells to display per direction, and `[size]` is the breakpoint at which to apply the effect.

<div class="callout primary">This example uses padding grid but this can be used with margin grid too.</div>

+Block Grids are not availaible for the vertical grids. Use the [basic layout](#vertical-grids) with a size applied on each cell of the grid instead.
