The question pretty much says it all.
For instance, if I were using, say, Twitter Bootstrap, could I define classes in my own SASS stylesheet that inherit from Bootstrap's CSS classes? Or does inheritance in SASS only work within the scope of a single file?
Just as the accepted answer has shown this is possible with @import, however @import has been deprecated by sass
The Sass team discourages the continued use of the @import rule. Sass will gradually phase it out over the next few years, and eventually remove it from the language entirely. Prefer the @use rule instead.
The @use rule is better suited for use now, since it does not pollute the scope of the importing (user) module. unfortunately at the time of writing the use rule is only implemented in Dart sass.
