April 2026 monthly summary: Delivered cross-repo accessibility improvements and fixes for arXiv/arxiv-browse and arXiv/arxiv-docs, with a strong focus on WCAG 2.2 remediation, keyboard navigation, and ARIA semantics. Key outcomes include: (1) arXiv/arxiv-browse: consolidated accessibility work addressing audit findings, including focus management for modals, proper ARIA roles for the mobile header, and tab navigation enhancements with focus-visible styling; improvements to Labstabs focus behavior and accessible SVG labeling; (2) arXiv/arxiv-docs: accessibility enhancements for contrast, visible link underlines, increased icon opacity for readability, and descriptive alt text for images. As a result, accessibility compliance improved across both platforms, user experience for keyboard and assistive-technology users strengthened, and audit-related risk reduced. Demonstrated skills include WCAG 2.2 remediation, ARIA patterns, focus management, focus-visible CSS, semantic HTML, accessibility testing, and cross-repo collaboration. Business value delivered includes wider audience reach, improved usability, regulatory compliance, and maintainability.
