Upgrade to Sass 3 #981
Description
Right now boostrap-slider generates a lot of deprecated warnings with the current Dart Sass, such as:
Global built-in functions are deprecated and will be removed in Dart Sass 3.0.0.
Using / for division outside of calc() is deprecated and will be removed in Dart Sass 2.0.0.
Sass @import rules are deprecated and will be removed in Dart Sass 3.0.0.
Getting dozens of deprecation warnings is a bit annoying. I'm aware these can be silenced, but this completely defies the purpose of having these warnings.
I'm creating this issue as a reminder for the future, and also as a Google sink so people looking up the warnings can find it and know it's being addressed and can thumb-up this rather than create new issues (I've searched and didn't find an existing one.)
