Provide sign language interpretation for prerecorded videos.
Why it matters: Some deaf users prefer sign language over text captions for comprehension.
Sign language interpretation is provided for all prerecorded audio content in synchronized media.
What This Means: This success criterion requires that prerecorded video content must have sign language interpretation available. Sign language is the primary language for many deaf users and provides better comprehension than text captions alone. The interpretation should be clearly visible and synchronized with the video content.
Why It's Important: While captions provide text access to audio content, sign language is the native language for many deaf users. Some deaf users have better comprehension in sign language than in written text, especially for complex concepts, emotional content, or when the user's first language is sign language. Providing sign language interpretation ensures the best possible access for this user group.
Sign language interpretation can be provided as a picture-in-picture video overlay, a separate video track, or a dedicated area on the screen. The interpreter should be clearly visible, well-lit, and positioned so they don't obscure important visual content. The interpretation should be synchronized with the video and cover all important audio information.
This criterion ensures that deaf users can access and understand the content, improving their overall experience and ability to use the website effectively.
This criterion ensures that sign language users can access and understand the content, improving their overall experience and ability to use the website effectively.
Impact: When this criterion is properly implemented, it removes barriers for these user groups and creates a more inclusive web experience for everyone.
A video has captions but no sign language interpretation.

Tip: Use this checklist during development and testing to ensure all requirements for 1.2.6 Sign Language (Prerecorded) are met. Check off items as you complete them.
Note: These are official W3C resources for 1.2.6. For the most up-to-date information and detailed technical guidance, always refer to the official W3C documentation.
Implementing 1.2.6 Sign Language (Prerecorded) correctly requires understanding your specific context. Code solutions vary significantly based on multiple factors:
HTML, React, Vue, Angular, PHP, Python, and other frameworks each have different patterns and best practices.
Server-side rendering, client-side rendering, static generation, and hybrid approaches require different solutions.
Your existing components, styling approach, and UI library influence how accessibility must be implemented.
Your specific user base, content type, and interaction patterns determine the most appropriate implementation.
We provide tailored implementation guidance by analyzing your specific technology stack, coding patterns, design system, and project requirements. Our team reviews your codebase and provides custom solutions that integrate seamlessly with your existing architecture.
