Tailwind is presented as a low-level, highly customizable CSS framework. It is called “low-level” because instead of offering predefined components, Tailwind offers utility classes: unlike other CSS frameworks such as Bootstrap or Foundation, Tailwind offers classes for our own HTML.

Most frameworks are not very efficient when it comes to customizing a website, due to their predefined and pre-designed components which “force” the user to do with what the framework offers. Tailwind does not provide predefined components designed in advance.

On the contrary, it provides customizable classes for those who want a personalized website, which stand out from the rest. It is becoming more popular than the historic Bootstrap. If you haven't tried it yet, now is the time!
