On tablet at a breakpoint of 600 dp this layout grid uses 24dp gutters.
Responsive grid gutter width.
The following examples show how the grid adjusts between key breakpoints on a communication site.
Notice that the grid uses box sizing.
Gutters are the space between the columns.
When you inspect the column mixin in the grid less file of the responsable framework you will find that each column got a padding on each side of half size the gutter width.
Just be sure to define your widths and gutters as percentage.
To make the grid responsive there are five grid breakpoints one for each responsive breakpoint.
On mobile at a breakpoint of 360 dp this layout grid uses 16dp gutters.

The standard bootstrap grid is a 12 column layout with a 15px margin on each side of the column.
20px is a common gutter size and this spacing will be really important when you have a masonry design or a grid of card elements a simple example being a photo gallery.
Using those we will be able to tell the grid to have a specific layout at certain device widths.
The masonry js library is freakin awesome.

Flex grid thirds col width.
On smaller screens it s like responsive.
Wider gutters are more appropriate for larger screens as they create more whitespace between columns.
Grid breakpoints are based on minimum width media queries meaning they apply to that one breakpoint and all those above it e g col sm 4 applies to small medium large and extra large devices but not the first xs breakpoint.
To make the grid responsive we will utilize media queries.
Resulting in a 30px gutter between columns plus 15px to the left and right of the grid.
