Gutter width in bootstrap 4.
It provides responsive mobile first fluid grid system which scales the columns as the device or viewport size increases.
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.
Offset md 3 means that the column moved by 3columns to the right if the viewport hits the md breakpoint or higher.
Bootstrap 5 comes with margin utilities.
Thanks for the response.
You can use predefined grid classes like col 4 or sass mixins for more semantic markup.

It takes a breakpoint and the size to move.
Offset md 4 means that the column moved by 4 columns to the right if the viewport hits the md breakpoint or higher.
Bootstrap 4 grid system built with flexbox which is fully responsive and scales up to 12 columns according to the size of device by creating layout with rows and columns across the page.
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.
We actually ended up just downloading the bootstrap source unzipping it copying the source scss files into the assets folder then importing the bootstrap scss file in index js instead of the final bootstrap css file.
The following approach will explain clearly.
Gutter space has width 30px 15px on each side of a column.
