Worked on the YOURLS/YOURLS repository to deliver accessibility-focused improvements to data tables, specifically enhancing the usability of action buttons for screen reader users. Addressed a screen-reader hover visibility issue by implementing an opacity-based show and hide mechanism, ensuring that interactive elements remain accessible without sacrificing usability for sighted users. Applied CSS and JavaScript to create aria-friendly controls and maintain a semantic table structure, aligning the interface more closely with WCAG guidelines. These changes broadened the potential user base and improved user satisfaction, all while maintaining minimal performance impact and demonstrating a thoughtful approach to frontend accessibility and inclusive design.
