How is the sass mixin currently being used?
After reading the documentation, I realized that they were used mainly so that the properties did not have to write prefixes for each browser, and now in 2019 how mixins are used, I would like to know?

Answer 2

To avoid code duplication, mixins should only be used if they must take arguments, and only to reduce code.
