I've just recently installed Visual Studio 2017 and Web Essentials 2017. Now i cant find the option to add missing vendor specifics in my scss files. Previously was using VS 2013 with Web Essentials 2013 and it had the option.
Any Ideas how i can get this back?
From the same creator of WebEssential you can download AutoPrefixer.
I hope in the future will be included in WebEssential, but for the moment you can download it separately.
