> Any selector has the potential to mess up the entire page. That's true, but the modern web stack has several solutions to this. If you don't mind "CSS-in-JS", I've been using the excellent styled-components [1] library for my company's React app. I believe Vuejs supports scoped styles out of the box [2]. And if you'd prefer to just write plain CSS, CSS modules [3] will mangle the classnames in your CSS files so you don't have to worry about collision.
