Questions about CSS framework

Is there any reason, why Joplin does not use, bootstraps, Bulma or any other CSS framework. Wouldn’t it make Styling easier and better, just a random thought!

@rishabh.malhotra please try not to ping either one of them. It’s a bit disruptive and someone will get to you when able to. Have you tried searching for the answer in the meantime? I don’t know the answer myself but it may have been acknowledged here already

Noted, I mean using a CSS framework is really subjective, I see more benefits to it than cons, it should make styling more standardized and easier.
