Hello everybody,
Maybe I’m doing something wrong. I tried taking a shot at Sage 10 and when doing yarn build:production, there are no vendor prefixes.
For e.g. with Sage 9, for transition
rules, I see -o and -moz but nothing with Sage 10.
Thanks for your help in advance,
Sam
Sage 10 uses Mix, which uses Autoprefixer, which looks at the browserlist
entry in package.json
to determine which browsers to target. In your case, it has determined that the browsers it is targeting do not need those prefixes. Check out Autoprefixer to see how you might customize that.
So I just needed to inspect another browser… 
Thank you so much @alwaysblank! I’m completely self-taught so I have to fill in the gaps as I go along.
