If you have experience with CSS, terms like padding, margin, and spacing will be familiar to you.
For instance, mb-0 translates to margin-bottom: 0;
Expanding on this concept, Bootstrap provides additional classes for handling margins:
mt- = margin-top
mb- = margin-bottom
ml- = margin-left
mr- = margin-right
my- = sets margin on y-axis simultaneously
mX- = sets margin on x-axis simultaneously

The best way to gain insight is by exploring the official Bootstrap site at https://getbootstrap.com. It offers comprehensive explanations of its ready-to-use classes.

As the top result for searching "class=mb-0", I want to point out that all previous answers are now outdated. In February 2022, Bootstrap has updated to version 5.1. Here is a link to the new spacing notation you should use in your classes: https://getbootstrap.com/docs/5.1/utilities/spacing/ (notably, left and right are now referred to as start and end in the new notation)
class="pd-1"
p - defines padding
d - specifies default padding
1 - sets 1 unit of padding
CSS class
.pd-1{
padding: 1rem
}
