eslint-plugin-css-custom-properties

ESLint plugin to lint CSS custom properties (CSS variables) in JavaScript template literals and strings. Version 1.1.0, released under MIT. Currently in active development with moderate release cadence. It focuses on detecting unknown, unused, or misused CSS custom properties within JavaScript code, which is useful for projects using CSS-in-JS or template literals for styling. Unlike generic CSS linting tools, this plugin operates inside JS strings, supporting ESLint >=7. Requires Node.js ^14.17.0 || ^16.0.0 || >= 18.0.0.
