So what is it?

Vanilla CSS is a tongue-in-cheek project that makes a simple joke: plain, ordinary CSS is already a framework. The pitch is that you don't need to download Bootstrap, Foundation, or any other styling toolkit to build a good-looking website. You can just write your own CSS from scratch. The README celebrates the idea that "vanilla" CSS, the standard styling language built into every web browser, is the fastest, lightest, and most widely used option out there, with a file size of zero kilobytes. The humor is in the presentation. The project lists major companies like Facebook, Google, and Netflix as "users," which is technically true because every website on the planet uses CSS at some level. It then provides straightforward examples of how to style elements, like turning a paragraph red or giving a specific section a background color. These examples are genuinely useful for someone learning the basics of web styling, even if the framing is playful. A beginner or non-technical founder building their first web page could actually follow the instructions here. The steps boil down to creating an empty file, linking it to your HTML document, and writing your own styling rules. There is nothing to install, no dependencies to manage, and no learning curve beyond understanding how CSS selectors work. The README points readers to standard reference materials like Mozilla's developer docs and Wikipedia for deeper learning. The project itself functions as both a joke and a gentle philosophy. It suggests that reaching for a heavy framework before you need one might be overkill, and that there is value in understanding the raw building blocks of the web. The team listing includes roles like "Lead Translator of UK to US english," reinforcing that the whole thing is delivered with a wink while still making a fair point about keeping things simple.
