Is it possible to access cssRules in Node JS
问题
I am attempting to modify CSS as part of a Node JS build process, but most of what I can find online refers to doing this in the DOM with Javascript. Is it possible to read a file in Node and access the equivalent of document.stylesheet or the cssRules property or is this a DOM-only concept and I need to stick with string replacement to modify these CSS rules/properties?
For reference here is the browser-based answer to the problem I'm trying to solve: Stack Overflow 上的回答

我认为使用DOM操纵CSS没有什么不好的，可以使用以下链接中的工具：https://www.npmjs.com/package/jsdom
如果要直接操作CSS，您可以将其解析为AST：
https://www.npmjs.com/package/css-tree
CSSTree是用于CSS的工具集：快速详细的解析器（CSS → AST），遍历器（AST遍历），生成器（AST → CSS）和词法分析器（基于规范和浏览器实现的验证和匹配）。主要目标是高效和符合W3C规范，重点关注CSS分析和源代码转换任务。

I think there's nothing bad to manipulate CSS with DOM, use for that: https://www.npmjs.com/package/jsdom
For manipulate CSS directly you could parse it into AST:
https://www.npmjs.com/package/css-tree
> CSSTree is a tool set for CSS: fast detailed parser (CSS → AST), walker (AST traversal), generator (AST → CSS) and lexer (validation and matching) based on specs and browser implementations. The main goal is to be efficient and W3C spec compliant, with focus on CSS analyzing and source-to-source transforming tasks.
