Bootstrap+css+scss?

Question

Bootstrap

Hello. Please advise how to properly organize work with Bootstrap? If earlier I created *.scss files myself, set styles in them and then collected all this using Grunt, then there were no problems. In the case of Bootstrap, there are default styles that need to be overridden and there are two main options: 1) include the bootstrap.css file, and add your own classes to override the Bootstrap styles in html; 2) Use sass, which can also be downloaded from the website. In the second case, how to use this file system? After all, it is not particularly recommended to change the contents of any of these files directly. As then?
In general, how to properly organize the use of sass bootstrap so that you can override the default styles and correctly use the provided features? Explain plz, or poke where you can read about it?

Answer 1

to override default styles, change the value of variables in sass.
