CSS in JS

JSS is an authoring tool for CSS which allows you to use JavaScript to describe styles in a declarative, conflict-free and reusable way.
It can compile in the browser, server-side or at build time in Node.

JSS 是一个 CSS 创作工具，它允许您使用 JavaScript 以声明性、无冲突和可重用的方式描述样式。
它可以在浏览器、服务器端或在 Node.js 的构建时编译。

JSS is framework agnostic.
It consists of multiple packages: the core, plugins, framework integrations and others.

JSS 与框架无关。
它由多个包组成：核心、插件、框架集成等。
