The earlier accessibility is considered in software delivery, the easier and cheaper it is to ensure what's built works for as many people as possible. Tools that help communicate accessibility annotations in designs help teams consider important elements like document structure, semantic HTML and alternative texts from the beginning of their work. This enables them to ensure user interfaces meet global accessibility standards and address common failures that are actually fairly easy to avoid. Figma offers a range of accessibility notation plugins: The A11y Annotation Kit, Twitter's Accessibility Annotation Library and the Axe toolset's Axe for Designers.
