Introduction

What is PikaCSS?

PikaCSS is an Atomic CSS-in-JS engine that allow you to write style in CSS-in-JS way and output in Atomic CSS way.

Inspired by UnoCSS, WindiCSS, TailwindCSS, StylifyCSS and Fela.js!

Why PikaCSS is been created?

<details> <summary>Click to 👀 the reason</summary>

I love the idea of Atomic CSS, there are many great Atomic CSS solutions out there, such as UnoCSS, WindiCSS, TailwindCSS, Stylify, etc.

Unfortunately, I am poor to memorize the utility class names, so UnoCSS, WindiCSS or TailwindCSS is not for me.

I am surprised by the zero learning curve concept of Stylify, but I don't like the idea of using a custom syntax to workaround the limitations of html class attribute.

To solve the problems above, the CSS-in-JS way is the best way to write styles, but it is not the best way to output styles.

So I created PikaCSS, it is a Atomic CSS-in-JS engine that allow you to write style in CSS-in-JS way and output in Atomic CSS way!
