Again, for ease of use - we have a library that provides us with none of the often clumsy overheads of managing a CSS framework in-house. We can develop user-interfaces and user-experiences at rapid speed using a pattern library that we can trust. We also have implemented some of the features of the TailwindUI library. However, access to the TailwindUI components is a "paid-for-service", but certainly allows our junior developers to understand good, clean, "compentised" and accessible UI/UX.
