Bootstrap 2-5 sucked, but it was great for throwaway internal tools that will never become public.
Foundation died to bootstrap.
Pure was made by yahoo and went unmaintained so some other people wanted something like pure but they wanted to monetize it, then Pure got remaintained by it’s community
Tailwind isn’t great, it sold devs on a lie by limiting choices to limit mistakes, but limiting choices also restricted the features that devs needed to do their projects properly. They tried to figure out a way to add those features but suffered from gradual scope creep while trying to maintain it’s original lie and has ended up more complicated than it needed to be while being less featureful than what devs needed. What they should have done instead of making everything a utility class, was keep the build system (lightning css), add a token system (e.g. open props, or their own version of it), allow people to add their own css instead of trying to shoehorn it into a class, then went out of their way to teach people how to make things as classless as possible.
Bulma.
Or if you need something smaller, simpler and more modular: purecss.io
(Yes it’s weird that they called a framework “pure” css, but it’s been a solid go to for a long time)
Pure has been around for a while. I’ve gone…
*Specific project hierarchy and postprocessing required. Unbeatable with a good pipeline, unusable without one.
