It is source map for Firefox and Chrome debuggers.
它是 Firefox 和 Chrome 调试器的源映射。

Because the source code is minified/bundled the line numbers do not refer to the orignal files. Source map protocol fixes this, allowing the web debuggers to refer to the original context from where the CSS was generated.
因为源代码被缩小/捆绑，所以行号不引用原始文件。源映射协议修复了这个问题，允许 Web 调试器引用生成 CSS 的原始上下文。
