Let's have a quick overview of the groundbreaking features of Master CSS:

- 🔓 Write CSS properties, functions, selectors and even media queries directly in class="...".

- 🧠 Automatically generate corresponding CSS rules based on class names.

- 💖 With enhanced CSS syntax, you can build UIs with less code.

- ⚡️ Directly use performant JIT in production. ~13KB

- 🧬 An enhanced and structured CSS syntax for class names.

- 🌈 A forerunner to syntax highlighting for class names.

- ✨ Hybrid Rendering that allows you topre-generate CSS from HTML on the server side, and then continue to use JIT on the client side.

- ✨ Group Styles that allows you to extract the same selectors and media query styles and make it short.

- ✨ Reactive Styles that allows you to style an element based on parent/sibling state.

Why Master CSS

A brief introduction starts by giving you an understanding of markup-driven CSS.

😐 Traditional

``` html
<style>
.home-section {
background-color: blue;
padding: 2rem;
text-align: center;
}
.home-section:hover {
background-color: red;
}
@media (min-width: 1024px) {
.home-section {
padding: 3rem;
}
}
</style>
<section class="home-section">...</section>
```

🤩 Now, refactor it with a whole new CSS language to make it easier. ↓ 86% code

``` html
<section class="bg:blue bg:red:hover p:32 p:48@md text:center">...</section>
```
