How to correctly override styles in scss libraries?

Question

css

There are sass component libraries: bourbon, bootstrap, materialize, etc. Some of the things in them are customized through variables, while others are defined in the style itself. How would it be correct to override such things? Here I have a .btn that has a shadow in it, I want to remove it - what is the best way to do this? Doing this directly in the library seems to be not accepted, overriding it in your styles produces css code.

Answer 1

Only to produce code is a fee for using any frameworks
But no one bothers you, for such a small thing as a button, copy the code from the framework and correct it for yourself by making .mybutton

Answer 2

In my own style, of course. The source code of the library should never be touched.

Answer 3

It happens that the library code needs to be replaced with a new version. And all your edits will fly ..
