We do not currently support audio and visual content on the website.
This can present barriers for some users, but it can enhance accessibility for others. Some users may prefer to access data in a non-text-based format.
When presenting data in an interactive format, provide the data being used as a downloadable CSV or XLS file.
When using audio or video content, always provide a transcript and captions. If the content is also on a third-party website, provide it there if possible. For example, on YouTube you should provide a transcript in the comments section and an option to turn on closed captions. As well as being helpful for users with visual or hearing disabilities, it allows all users to download the information for offline use to read in their own time.
When using video or audio content, avoid flashing lights and images, which can cause seizures, and keep distracting background noise to a minimum.
We are constantly improving based on research and best practice. Any significant changes to our guidance are available on the Updates page.
