Closed captioning is a process of displaying text on a video screen to provide a textual representation of the audio content. It is primarily used to assist individuals with hearing impairments in understanding the dialogue and sounds in a video.
HTML provides several elements to implement closed captioning, such as the
<track> element. This element is used within the
<video> tag to specify a text track file containing the closed captions. The captions are then displayed on the video screen when enabled by the viewer.
By incorporating closed captioning in HTML, video content becomes more accessible and inclusive, ensuring that everyone can enjoy and understand the audiovisual content.
