What is que prefix for edge?

Answer 1

Hi David, I found this: isting prefixed properties that are hugely popular will remain until they have native support, but Microsoft Edge will not be introducing a new prefix system for features. Instead, they'll use feature flags (like Chrome and Firefox for experimental features on the client side, rather than the developer side).
The inconvinient is that they removed the support for -ms- prefix. what a mess
