Contributed accessibility enhancements to the WordPress/gutenberg repository, focusing on the Image and Breadcrumbs blocks within the editor. Delivered a feature that introduced a 'Mark as decorative' toggle for images, updating alt text handling and inspector controls to better support assistive technologies. Improved navigation for screen reader users by hiding breadcrumb separators, aligning the editor more closely with WCAG standards. Collaborated closely with other contributors, consolidating changes into cohesive, multi-author commits to streamline code review and maintenance. Utilized JavaScript, React, and CSS to implement these front end improvements, ultimately supporting broader user adoption and reducing accessibility-related risks in the editor.
