analysis or mutation of CSS source code should be done with the least powerful tool that can accomplish the task. + * For many applications it is sufficient to work with tokens. + * For others you might need to use {@link https://github.com/csstools/postcss-plugins/tree/main/packages/css-parser-algorithms | @csstools/css-parser-algorithms} or a more specific parser. + * + * @example + *
