Long Description

A detailed textual description of an image or other non-text content that goes beyond the brief summary provided by alt text. Long descriptions are used for complex images such as charts, diagrams, infographics, or detailed illustrations where a short alt text cannot convey all the meaningful information. Unlike alt text, which is typically placed in an HTML attribute, long descriptions are usually included in the body of the page or linked via mechanisms like the aria-describedby attribute or a visible text block, making them available to all users including those using screen readers, magnification, or other assistive technologies.
