Accessible Rich Internet Applications, or ARIA, is a set of attributes that are added to the code for interactive elements on web pages.

Some Valuable Tips When Creating Accessible Rich Internet Applications
Accessible Rich Internet Application (ARIA) is a W3C standard that defines the methods and forms of rich media access that are commonly used on the web.
It consists mainly of an XML syntax extension that is used to define the actions and state changes that are involved in defining rich media objects or any other type of media object. In simple terms, it defines how an author can create rich media access by writing XML documents. In this case, XML is again used as a means of representing the document and the actions associated with it in terms of its content. As a result, the manipulation of these documents becomes possible through the use of data transformations.
Accessible Rich Internet Applications: Tiled layout
One popular application of Accessible Rich Internet Applications is the tiled layout. The basic module of this technology allows users to create a number of tiled panels that are then arranged in the tab order. The tiled layout allows the author to arrange the content horizontally or vertically. Tab order allows users to arrange the panels in a way that scrolls horizontally. This is useful when there is a large amount of content or if the content needs to be scrolled.
Another example of Accessible Rich Internet Applications is the usage of accessible widgets.
A widget is a piece of information that web users can add to their web pages. There are many different types of accessible widgets, such as:
- radio buttons;
- search boxes;
- pop up boxes;
- text boxes.
A widget can change the appearance of the web page by using appropriate color or style elements. The term widget attribute refers to the HTML or XHTML codes that make aria use a container for the elements that it contains. These are required because aria uses tables, lists of elements. An example of a widget is a form or check box. In the example above, the aria use would be the form element and the check box would be the input element.
The aim of Accessible Rich Internet Applications
The aim of Accessible Rich Internet Applications is to provide a way for individuals to take full advantage of online applications, whether they are desktop-based or mobile-based. This aim is to ensure that users have access to websites, regardless of whether they are on a personal computer, a tablet PC, a smartphone, an internet-connected TV screen, or a hand-held device. This aim was announced at the World Wide Web summit in May 2021. The aim was to set the standards for web applications by creating a specification called W3C WAAS or what is known as the World Wide Web Accessibility Initiative.
Ways to accessibility
There are different ways on how accessible otherwise would be created. First of all, we have the invisible ARIA. This is one of the more complicated aria’s to create because it requires the developer to provide something that will act as both a label and a container for the aria. To make this a bit easier, there is an aria-hidden attribute. An example of an element that has an aria hidden is the input element.
Next, there is the aria-enabled attribute where one can specify whether particular elements should be able to be viewed even if the aria is hidden or disabled. It also specifies whether other elements should be disabled in the same way. The aria-invisible attribute allows the user to toggle whether aria is visible or invisible. There are also times when an aria-invisible is not needed and in such cases, it would be best to not include it in the ARIA layout.
Other than those mentioned, there are actually many other attributes that can help web developers create more assistive web pages. In the case of the aria, it provides structure to the HTML elements and helps in creating a more search engine-friendly layout. Basic knowledge of aria-hidden and aria-enabled is beneficial but not enough.
