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.
Gutter width bootstrap 4.
This is done by using padding.
Things to remember with grids containers.
In bootstrap 4 there are 12 columns in the grid system each column has a small space in between that space is known as gutter space.
The gutter width is 30px.
Note that with the introduction of version 4 bootstrap now uses a 5 tier grid system as opposed to the 4 tier grid system in bootstrap 3.
With its latest version bootstrap 4 4 1 currently in live bootstrap 4 is a major rewrite of its previous version.
There are a lot of changes from its previous versions in terms of bootstrap components and visual appearances.
Bootstrap 5 comes with margin utilities.
The following approach will explain clearly.
The bootstrap 4 grid system has five classes col extra small devices screen width less than 576px col sm small devices screen width equal to or greater than 576px col md medium devices screen width equal to or greater than 768px.
Offset md 4 means that the column moved by 4 columns to the right if the viewport hits the md breakpoint or higher.
The gap between the column content is called gutter.
15px on each side of the column.
Thanks for the response.
You may remove the gutter by using no gutters in the row.
An example of equal width in all devices.
Offset md 3 means that the column moved by 3columns to the right if the viewport hits the md breakpoint or higher.
Bootstrap 4 has been in alpha for almost 2 years.
30px 15px on each side of a column nestable.

Bootstrap 4 grid system.
Use the powerful mobile first flexbox grid to build layouts of all shapes and sizes thanks to a twelve column system five default responsive tiers sass variables and mixins and dozens of predefined classes.
Variables and maps determine the number of columns the gutter width and the media query point at which to.
By using the col or col you will make bootstrap handle the layout automatically on all devices.
It takes a breakpoint and the size to move.
