Importing bootstrap.css vs bootstrap.min.css

[hossameldeen]

If I import bootstrap.css, will there be any difference in the production build from if I've imported bootstrap.min.css?

React-Bootstrap docs give an example of importing bootstrap.min.css. However, Create React App docs seem to indicate one should import bootstrap.css instead.

Of course, I'd prefer to import boostrap.css in case this has any enhancement in the developer experience. But I wouldn't want to incur any cost (nor add source maps?) on production.

If I import bootstrap.css, does CRA do some magic by which the production build is equivalent to having imported bootstrap.min.css?
