Contributed to the freeCodeCamp/freeCodeCamp repository by developing an interactive lesson update focused on accessibility education. The work centered on implementing hands-on ARIA-live examples within the curriculum, allowing learners to observe real-time screen reader behavior. Using HTML, CSS, and JavaScript, the update introduced testable code samples that demonstrate the practical application of the aria-live attribute, enhancing the inclusivity of learning materials. Collaboration with another contributor ensured thorough code review and curriculum alignment. This feature strengthened the accessibility component of the core curriculum, providing a more engaging and effective educational experience for users seeking to understand front-end accessibility patterns.
