Rule
The name, role, value, states, and properties of user interface components MUST be programmatically determinable by assistive technologies.
Background
If a set of carousel slides, thumbnails, or "dots" indicate visually which slide is currently selected - such as with an outline, underline, color change - the same information must also be conveyed programmatically to people who cannot see the content.
How to Fix
Fix this issue by using aria-current="true" on the container of the current slide (<a>, <button>, <img>, <div>...)
