Captions are the simplest way to make a video accessible for the visually impaired. “Open captions" refer to subtitles that appear on the screen whether the viewer chooses to see them or not; “closed captions” may be toggled by the viewer and often provide details about digetic sound such as doors closing. Captions should be placed at the bottom of the screen to avoid interfering with visuals. Captions are generally displayed in two lines, each with a maximum of 32 characters.
