Web Accessibility Remediation
Once an accessibility audit has been conducted, and accessibility errors have been identified, the errors will need to be remediated in order to ensure the site is compliant with accessibility errors. The traditional way of correcting an inaccessible site is to go back into the source code, reprogram the error, and then test to make sure the bug was fixed. If the website is not scheduled to be revised in the near future, that error (and others) would remain on the site for a lengthy period of time, possibly violating accessibility guidelines. Because this is a complicated process, many website owners choose to build accessibility into a new site design or re-launch, as it can be more efficient to develop the site to comply with accessibility guidelines, rather than to remediate errors later.
With the progress in AI technology, web accessibility has become more accessible. With 3rd party add-ons that leverage AI and machine learning, it is possible to offer changes to the website design without altering the source code. This way, a website can be accessible to different types of users without the need to adjust the website for every accessibility equipment.
Accessible Web applications and WAI-ARIA
For a web page to be accessible all important semantics about the page's functionality must be
available so that assistive technology can understand and process the content and adapt it for the
user. However, as content becomes more and more complex, the standard HTML tags and attributes
become inadequate in providing semantics reliably. Modern Web applications often apply scripts to
elements to control their functionality and to enable them to act as a control or other dynamic
component. These custom components or widgets do not provide a way to convey semantic information to
the user agent. WAI-ARIA (Accessible Rich Internet Applications) is a specification published by
the World Wide Web Consortium that specifies how to increase the accessibility of dynamic content
and user interface components developed with Ajax, HTML, JavaScript and related technologies. ARIA
enables accessibility by enabling the author to provide all the semantics to fully describe its
supported behaviour. It also allows each element to expose its current states and properties and its
relationships between other elements. Accessibility problems with the focus and tab index are also
corrected.
