Sublime text 3 autoprefixer not working?

Question

css

The question has already been raised here more than once, but I don’t even get an error.
The node is installed, for example, I enter d isplay: flex;, I press the auto-prefix, it thinks for a couple of seconds, but in the end it adds nothing and there are no errors. What could be wrong with him?

Answer 1

The autoprefixer (at least the one for the gallp plugin) works based on caniuse data. Perhaps they already think that adding prefixes is not worth it for flex?
Judging by the table ( https://caniuse.com/#search=flex) - yes, prefixes are not needed. Check with something newer that is guaranteed to be supported with prefixes

Answer 2

Connect a third-party autoprefixer to the project and configure it as you like. Tomorrow Sublime will be updated and something will break. Or suddenly you switch to Vidual Code, WebStorm etc.
