Responsive Grid Gutter Width

The standard bootstrap grid is a 12 column layout with a 15px margin on each side of the column.

Responsive grid gutter width.

On smaller screens it s like responsive. All breakpoints extra small small medium large and extra large. To make the grid responsive there are five grid breakpoints one for each responsive breakpoint. To make the grid responsive we will utilize media queries.

Just be sure to define your widths and gutters as percentage. Gutters are the space between the columns. On mobile at a breakpoint of 360 dp this layout grid uses 16dp gutters. Leveraging the column mixin you can set the second argument to 0 to remove the padding gutter.

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. 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. To better adapt to the screen gutter width can change at different breakpoints. That s because of the goodness baked right into the responsive grid system.

Flex grid thirds col width. Resulting in a 30px gutter between columns plus 15px to the left and right of the grid. Small 320 x 568 the small size has a single centered column area with 20 px margins left and right. 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. Border box see also why did bootstrap 3 switch to box sizing. The maximum width of the content area of a communication site is 1204 px and the minimum size is 320 px for mobile support. On tablet at a breakpoint of 600 dp this layout grid uses 24dp gutters.

Notice that the grid uses box sizing. The following examples show how the grid adjusts between key breakpoints on a communication site. If you go the flexbox route you also now have the ability to change the order of columns as needed which can be great for keeping more important content higher in the source as well as responsive design reshuffling. From our notes we want both main and sidebar elements to be 100 width for mobile then both 50 side by side on tablet and then 2 3 and 1 3 width side by side on desktop.

Using those we will be able to tell the grid to have a specific layout at certain device widths. Provided you re looking at it on a screen larger than 768 pixels wide.
