Sass library is a toolkit of mixins and resources designed to make styling with SCSS as efficient by flexible as possible.
$ npm install sass-library
Alternatively include the files manually if you aren't using a package manager.
@import '~sass-library/mixins/prefix.scss';
@import '~sass-library/mixins/visibility.scss';
.some-element {
@include prefix(display, flex, ms webkit);
}
