ARIA15: Using aria-describedby to provide descriptions of images: Example
This example web page uses the technique described at ARIA15: Using aria-describedby to provide descriptions of images. It is meant to be used for screen reader testing.
The objective of this technique is to provide descriptions of images when a short text alternative does not adequately convey the function or information provided in the object.
The following example shows how aria-describedby can be applied to an image to provide a long description, where that text description is on the same page as the image.
