When looking at some websites, you can tell that it was built using a certain CSS framework.
Whether it's using a standard component like a navbar or card, or it's using the default colour palette, you can confidently know that website uses ___.
As Tailwind includes no components (other than the container) and only has low-level utility classes for things like spacing and colours (amongst many other things), you can build radically different-looking websites with the same classes.
