In April 2025, Eduard Akhmetshin developed a new linting rule for the stylelint/stylelint repository, focusing on enforcing consistent color function alias notation in CSS. He implemented the color-function-alias-notation rule, which allows teams to configure whether rgb()/hsl() or rgba()/hsla() should be used, supporting both with-alpha and without-alpha options. Eduard wrote comprehensive tests and documentation to ensure the rule’s reliability and ease of adoption. His work, primarily using JavaScript, CSS, and Node.js, improved code quality by reducing lint churn and promoting uniform color function usage, reflecting a thoughtful approach to maintainable stylesheet linting practices.
