Bootstrap grid is a system of columns and rows which is used for creating a page layout.
This is because the viewport width is in pixels and does not change with the font size.
Every column have a padding of 15 px on both sides.
In the case of the sm grid your container class will 970px 940px grid gutter width.
Every column get a width of 940 12.
One big advantage with flexbox is that grid columns without a specified width will automatically layout as equal width columns.
Which makes a gutter between of 30 px.
See how aspects of the bootstrap grid system work across multiple devices with a handy table.
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.
Variables and maps determine the number of columns the gutter width and the media query point at which to begin floating columns.
Thanks for the response.
The biggest difference between bootstrap 3 and bootstrap 4 is that bootstrap 4 now uses flexbox instead of floats.
In bootstrap 3 the gutter is defined as 30px 15px on each side of a column.
