Accessible Rich Internet Applications (ARIA) is a set of roles and attributes that define ways to make web content and web applications (especially those developed with JavaScript) more accessible to people with disabilities.
It supplements HTML so that interactions and widgets commonly used in applications can be passed to assistive technologies when there is not otherwise a mechanism. For example, ARIA enables accessible JavaScript widgets, form hints and error messages, live content updates, and more.
The first rule of ARIA use is "If you can use a native HTML element or attribute with the semantics and behavior you require already built in, instead of re-purposing an element and adding an ARIA role, state or property to make it accessible, then do so."
Here's the markup for a progress bar widget:
This progress bar is built using a , which has no meaning. We include ARIA roles and properties to add meaning. In this example, the role="progressbar" attribute informs the browser that this element is actually a JavaScript-powered progress bar widget. The aria-valuemin and aria-valuemax attributes specify the minimum and maximum values for the progress bar, and the aria-valuenow describes the current state of it and therefore must be kept updated with JavaScript.
Along with placing them directly in the markup, ARIA attributes can be added to the element and updated dynamically using JavaScript code like this:
Like any other web technology, there are varying degrees of support for ARIA. Support is based on the operating system and browser being used, as well as the kind of assistive technology interfacing with it. In addition, the version of the operating system, browser, and assistive technology are contributing factors. Older software versions may not support certain ARIA roles, have only partial support, or misreport its functionality.
It is also important to acknowledge that some people who rely on assistive technology are reluctant to upgrade their software, for fear of losing the ability to interact with their computer and browser. Because of this, it is important to use semantic HTML elements whenever possible, as semantic HTML has far better support for assistive technology.

Unter einer Arie versteht man ein solistisch vorgetragenes Gesangsstück in der klassischen Musik. Eine dazugehörige Instrumentalbegleitung kann von der reinen Continuo-Begleitung mit nur einer Laute oder einem Cembalo, über ein kleines Ensemble mit einem oder mehreren Solo-Instrumenten bis hin zu einem großen Orchester gehen ...
