Gutters are the padding between your columns, used to responsively space and align content in the Bootstrap grid system. Read the Official Bootstrap Documentation for a full list of instructions and other options.
Gutters can be responsively adjusted. Use breakpoint-specific gutter classes to modify horizontal gutters, vertical gutters, and all gutters.
Like the horizontal gutters, the vertical gutters can cause some overflow below the .row at the end of a page.
Classes .g-* can be used to control the horizontal gutter widths, for the following example we use a smaller gutter width, so there won’t be a need to add the .overflow-hidden wrapper class.
The gutters between columns in our predefined grid classes can be removed with .g-0. This removes the negative margins from .row and the horizontal padding from all immediate children columns.
