Summary

Section titled “Summary”

Embedded content is a separate file that is placed (embedded) into an application. An example of embedded content is a YouTube video displayed within a web page. The most common types of embedded content are video, audio, SVG, CANVAS, and iframe elements.

Much like images, embedded content needs a text alternative to be understood by people using assistive technologies. You can supply the text alternative with an alt text, title, label, or other naming methods.

Overview

Section titled “Overview”

Embedded content consists of a separate file not created in the current website that is placed into the site. Embedded objects are self-contained and can work independently from the application in which they are embedded.

The most common types of embedded content are video and audio files, embedded SVG files, and CANVAS files. Files can also be embedded using <frame>, <embed>, or <object> elements, but this is discouraged as these methods of embedding files are not as well supported by assistive technologies.

All embedded files must have alternative (alt) text.
