WCAG: 2.4.1, 4.1.2: Frames must have title attribute

All frame or iframe elements in the document must have a title that is not empty to describe their contents to screen reader users.

Screen reader users rely on a frame title to describe the contents of the frame. Navigating through frame and iframe elements quickly becomes difficult and confusing for users of this technology if the markup does not contain a title attribute.

Screen reader users have the option to pull up a list of titles for all frames on a page. Adding descriptive, unique titles allows users to quickly find the frame they need. If no titles are present, navigating through frames can quickly become difficult and confusing. If no title is listed, screen readers will instead give information like “frame,” “JavaScript,” the filename, or the URL. In most cases, this information won’t be very helpful.
