ARIA
Abbreviation for Accessible Rich Internet Applications
In short and in plain language
ARIA is an extra part of the code of web pages.
It describes buttons and other controls for helper tools. One example is a screen reader, which reads the screen aloud.
The right roles help a website to be read out clearly. This is true for menus, forms and notices.
Definition
ARIA is an extension to HTML that describes interface elements for assistive technologies such as screen readers. Correct ARIA roles help menus, forms and notices on a website to be read out in an understandable way.
