Akos Horvath enhanced the accessibility of the Block Content Editor within the instructure/canvas-lms repository, focusing on improving usability for assistive technology users. He implemented UI refinements such as adding a close button to the accessibility checker and adjusting navigation control alignment. Using React, JavaScript, and TypeScript, Akos refined ARIA labeling so the accessibility checker button dynamically reports the number of issues found, providing clearer feedback for screen reader users. His work aligned with WCAG principles, addressing inclusive design and compliance. The updates demonstrated a thoughtful application of accessibility best practices and contributed to a more robust, user-friendly front-end experience.
