Other requirements

In addition to having good heading structure, alternative text for images, and descriptive links. Your website must also have:

• Closed captioning for all videos that are embedded (Level A).
• Transcript for all podcasts and audio (Level A).
• A text alternative for any videos without sound or videos that only contain music (Level A).
  • In other words, provide a simple text description of what's happening on screen below the video, so people who are blind can understand what is happening in the video. 
  • Alternatively, consider providing at least a voice over of any on-screen text elements, or provide audio description for your videos if possible. Audio description is not mandatory, however highly encouraged.
• Avoid images of text whenever possible (Level AA).
• Animations (such as GIFs) that are longer than 5 seconds or loop infinitely must have the ability to be paused. 
  • Note: Any images uploaded to AEM that have a .gif file extension will automatically receive a pause button. If an animation is longer than 5 seconds or contains important information, consider replacing it with a video instead.
  • If an animated .gif is less than 5 seconds long, you can prevent a pause button from being added by including the text 'gifa11y-ignore' in the file name or by adding a CSS class of 'gifa11y-ignore' to the image via the HTML component. Static images should always be saved as JPG or PNG.
