PROFILE
Andrew
Andrew Milne contributed to the ONSdigital/design-system repository by delivering accessibility-focused enhancements, UI consistency improvements, and security fixes across six features and three bug fixes over five months. He refactored navigation and table-of-contents components for better accessibility and maintainability, standardized CSS class naming, and introduced utility SCSS classes to improve spacing flexibility. Using JavaScript, SCSS, and Nunjucks, Andrew addressed cross-site scripting risks in autosuggest components and improved character counting logic for textareas. His work emphasized test reliability, code readability, and alignment with WCAG standards, resulting in a more robust, maintainable, and secure front-end design system for ongoing development.

Jul 1, 2025In July 2025, delivered two targeted changes in ONSdigital/design-system that improve user interface consistency and security, reinforcing business value through reliable components and safer user interactions. The Card Heading Spacing Consistency fix aligns typography across card components by adjusting CSS to prevent unintended top margins for h2 within ons-card__title. The Autosuggest XSS Mitigation adds sanitization of user-generated content prior to DOM rendering, closing a client-side XSS risk flagged by code scanning. Together, these changes reduce visual defects, mitigate security risk in user-visible components, and improve maintainability of the design system. Key technologies: CSS, DOM sanitization, secure rendering practices; evidenced by commits 6fd9d39c4a4224676e032cbc005e6d1f5ff8d4d8 and 6ed76511686516ce1f8c7d0cceaa55bf11c41754, aligned with ONSDESYS-555 and #3696.

Jan 1, 2025January 2025 — Monthly summary for ONSdigital/design-system. Delivered two high-value changes focused on accessibility and correctness, directly enhancing user experience and design-system reliability. Implemented accessible base font size by adjusting HTML font size calculation to 100% to respect user browser font size settings (commit d3d57339e3c69bbdec7cce6e8f208acbb3a741eb). Fixed footer copyright rendering by refactoring string concatenation from '+' to '~' to align with template best practices (commit 2027b02f283fbc0b3775296a249b8cfb34817229). These changes improve WCAG alignment, reduce risk of mis-rendered notices, and improve maintainability across the design-system.
