This question is about how to disable selection of DOM elements via user interaction. (This is wildly important for some rich HTML apps like games.)
The most common solution is the user-select: none
CSS rule (plus its browser-specific variants) which indeed does the trick for now.
However, a comment mentions that this feature was only a draft and isn't present in the current CSS specification.
What's the story here? Was this feature renamed or perhaps was it made obsolete on purpose? Can I count on this feature to remain functional or should I start implementing it differently or avoid it altogether?
