Accessibility / Media / Media Captions Checker Bookmarklet

The Media Captions Checker bookmarklet reports caption status, autoplay, and controls for video and audio elements. Finds all video and audio elements, checks for caption/subtitle tracks in textTracks, reports autoplay attribute status, reports controls attribute status, and displays an alert with each media element's status in the format: "TAG captions:yes/no autoplay:yes/no controls:yes/no". Useful for verifying media accessibility. No media found shows "No media found" alert..
