I like Tailwind and I'm not a fan of Bootstrap, but I don't think they're targeted at the same crowd at all.<p>Tailwind and other utility frameworks aim to solve (well, avoid) the naming problem, and address the common tendency for a project's CSS to devolve into hyper-specific rules where you can't modify or remove anything for fear of breaking something else. The downside is that it doesn't provide any pre-made components for you—you've either got to build them yourself or use something someone else has built.<p>Bootstrap, Bulma, etc. are largely focussed on providing pre-made components (albeit with some utility classes), with the downside that making one-off modifications (e.g. "I want this panel, but in this one specific place it needs to have no bottom margin") is typically very awkward—or at least was in the Bootstrap 3 days; admittedly I haven't really used 4 or 5.
