How to undo bootstrap pranks?

Question

css

Hello! And actually to the question:
Such a code will look crooked in ie because at the top there is a line-height property: 1.42857143 which affects the code in such a way, this property from the bootstrap is not strange (it is one of the bootstrap, the rest of the code is mine).
Question: how to cancel (override) this weight?)

Answer 1

I'll tell you more. It also looks crooked in firefox. And even if you remove the line-height property, or if you set it to 0 or 100.
What does line-height have to do with it?
Firefox has an extra padding. Removed like this:
