The Accessibility Gap: Why Semantic HTML Deletion Tags Aren't Enough Across Browsers

This article exposes a critical inconsistency in browser support for semantic HTML deletion and insertion tags across different screen readers and operating systems. While `<del>` and `<s>` tags are designed to communicate content changes through ARIA mappings, their actual support ranges from fully announced to completely ignored depending on the browser-OS combination. Developers must supplement semantic tags with visually hidden contextual text to ensure all users—including those relying on assistive technologies—receive meaningful information about price changes and content modifications.
