Worked on the mozilla/gecko-dev repository to enhance CSS validation by updating and expanding test coverage for custom properties and computed styles. Focused on ensuring that color values, including currentcolor and color-mixing, resolve correctly and that image values are validated as absolute URLs. Improved the reliability of the test harness and helpers to reduce flaky results and support continuous integration confidence. Addressed updates to the CSS Progress() function by reflecting new clamping behavior, adding out-of-range value coverage, and removing obsolete tests. Utilized JavaScript, CSS, and web platform testing skills to deliver robust, traceable bug fixes supporting release readiness.
