Overview. ARIA is a W3C specification that stands for Accessible Rich Internet Applications. It consists of markup that can be added to HTML to convey the roles, states, and properties of user interface elements to assistive technologies (AT).
Definition. aria-label is an attribute defined in the WAI-ARIA(opens in a new tab) specification. This specification extends native HTML and allows you to change the way an HTML element is “translated” into the accessibility tree. By default, an HTML element uses its textual content as the accessibility label.
ARIA roles give content semantic meaning, allowing screen readers and other tools to present and support interaction with objects in a way that reflects user expectations of that type of object.
WAI-ARIA refers to the Web Accessibility Initiative – Accessible Rich Internet Applications. WAI-ARIA is a technical specification written by the World Wide Web Consortium (W3C). The specification is most commonly used by developers to create interactive website content that is accessible to people with disabilities.
Description. The aria-valuenow attribute defines the current value for range widgets. It is similar to the value attribute of <progress> , <meters> , and <Input> Type range , number and all datetime types.
aria-label should be used in conjunction with the title attribute. Aria for screen readers and title attribute for others who want more information about the button’s action.
While there are 35 aria properties and states that the W3C defines that you can read more about on the W3C site, here are what we think are the most commonly used and are useful for most websites/applications.
aria-disabled (state) Indicates that the element is perceptible but disabled, i.e. not editable or otherwise operable. See related aria-hidden and aria-readonly. Aria drop effect.
The aria-controls attribute identifies the element (or elements) whose content or presence is controlled by the element on which the attribute is set, regardless of what type of interaction triggers the affected behavior.
Description. The aria-hidden attribute can be used to hide non-interactive content from the accessibility API. Adding aria-hidden=”true” to an element removes that element and all of its child elements from the accessibility tree.
By the beginning of the 18th century, composers such as Alessandro Scarlatti had established the aria form, and in particular its da capo version with ritornellos, as a key element of opera seria.
