During February 2026, contributed to the exelearning/exelearning repository by designing and implementing an Accessibility Toolbar feature that enables users to toggle all on-screen text to uppercase. This feature was developed using CSS, JavaScript, and TypeScript, integrating seamlessly with the existing accessibility framework. The solution included UI enhancements, keyboard navigation support, and ensured compatibility with screen readers to improve usability for diverse users. User preferences were persisted via localStorage, providing a consistent experience across sessions. The work focused on backward compatibility and minimizing disruption, aligning with accessibility guidelines to enhance readability options without introducing new bugs or regressions.
