How to increase margin/padding in Bootstrap?

Question

css

by default m-5/p-5 has a value of 3rem, how to increase this value?
I don't even understand, or do I need to do it with css?

Answer 1

This is a set of default indentation utilities that you want from them.
You can override them in the source. But why, if one way or another in 99% of cases you will write styles for your element. Write padding for this element in your css

Answer 2

First, don't use bootstrap. It used to be a good library, but now it's not needed. Got Flexbox!
Secondly, according to the experience of using bootstrap. If you are changing the standard indentation, then you are doing something wrong. Most likely, by fixing one indent, you will pin the entire layout on crutches.
And finally thirdly. Nothing prevents you from doing this and finally breaking everything:

body .m-5, body .p-5 {
    padding: 0 5rem;  /* Если не сработает, то исправьте на padding: 0 1rem !important; */
}
