Merged
requested to merge github/fork/andrewywong/move-away-from-node-sass-and-update-related-docs into master
Created by: andrewywong
In addition to updating the docs to reference sass and its latest features, I've also updated the docs to reflect the fact that we don't need the '~' prefix to resolve modules from node_modules anymore.
Closes #10045 (closed), closes #10771 (closed)
