Using the aria-labelledby attribute - Accessibility. Description The aria-labelledby attribute contains the element IDs of labels in objects such as input elements, widgets, and groups.
The attribute establishes relationships between objects and their labels. Assistive technology, such as screen readers, use this attribute to catalog the objects in a document so that users can navigate between them. Without an element ID, the assistive technology cannot catalog the object. aria-labelledby is very similar to aria-describedby: A label provides essential information about an object, while a description provides extended information that the user might need. In addition to form elements, you can use the aria-labelledby attribute to associate static text with widgets, groups of elements, panes, regions that have a heading, definitions, and other types of objects.

It was a veritable blast, and the conference organizers were certainly a pleasure to work with. I won’t delve into a lengthy play-by-play coverage of the proceedings; Andy Budd seems to have done so nicely. Without blatant disregard to humility, I’d like to think I delivered the most effective presentation I’ve given to date, but one never knows for sure just how well a topic resonates with the audience.
