Context for people who don't get the joke, the logo on the right is for Tailwind, a library that offers an alternative to using normal CSS for styling Web UIs and websites.

It provides you with microclasses that add flexbox, margins, shadows etc. and discourages you from using the "Cascading" part of CSS (which was likely a mistake imo)

Ultimately, it's still CSS under the hood which is the joke.
