Web Content Accessibility Guidelines (WCAG) 2.1 are the latest standards for digital accessibility of web content on desktops, laptops, tablets and mobile phones. These guidelines aim to make web content more accessible and user-friendly to people with various disabilities including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities. By making their websites WCAG 2.1 compliant, companies can reach a wider audience.
WCAG 2.1 is an updated version of Web Content Accessibility Guidelines 2.0 (WCAG 2.0), published in 2008. Since technology evolved quickly, the standards too, needed to evolve to ensure that people with disabilities were able to access the digital ecosystem. The WCAG 2.1 was created by the W3C, a private organization comprising of stakeholders from various sections of the society including government, industry, and consumer groups. The web content that conforms to WCAG 2.1 also conforms to WCAG 2.0, or in other words, WCAG 2.1 does not depreciate or supersede WCAG 2.0. Rather, it seeks to maximize future applicability of accessibility efforts. This standard can also be used by organizations for referencing in procurement or litigation.
WCAG has added 17 new success criteria – 5 level A criteria, 7 level AA criteria and 5 level AAA criteria. The success criteria are mostly related to mobiles, small screens and touch screens, and have been incorporated to make digital content more accessible to users with low vision, cognitive, vestibular, motor and dexterity disabilities. WCAG 2.1 also brings in a new guideline on input modalities and a new conformance requirement note. Besides, these new guidelines also support Accessibility Management Platform (AMP).
What’s New in WCAG 2.1
WCAG 2.1 includes 17 new compliance standards that place a higher emphasis on functionality and mobile optimization. The highlights include:
- Mobile accessibility
- Limits on interruptions, like pop-ups
- Improved navigation technology to reduce clicking on incorrect links or button
- New standards benefit low vision users; these include 400% zoom, 3:1 contrast level, and better labelling
Now let us see some of the benefits of having a WCAG compliant website:
- Avoids Discrimination and Legal Complications
- Builds Positive Public Relations
- Better SEO (Search Engine Optimization)
- Improves Usability for All Visitors
- Broadens Your Market Penetration
Here is a brief description of some of the new success criteria for WCAG compliance:
Identify Input Purpose (AA): Values must be auto-filled in the input field as it will be difficult for people with dexterity issues to type.
Identify Purpose (AAA): The links, buttons, regions and icons on a website are marked up to enable users to personalize and use their own icons and links.
Timeouts (AAA): Users are warned of the duration of inactivity to prevent data loss.
Reflow (AA): Text and other content on a page should reflow without causing any loss of content or functionality. This criterion has been developed to support users who use zoom on their desktops and is not much applicable on mobile.
Non-Text Contrast (AA): Buttons, form fields, focus indicators, and selected state indicators should have a contrast ratio of least 3:1 contrast with adjacent colors to allow low-vision users to identify features of controls.
Text Spacing (AA): This criterion seeks to ensure that there is no loss of content or functionality while increasing the space between lines, words and letters to enable better readability.
Content on Hover or Focus (AA): This criterion is implemented via the escape key to allow users to dismiss content that blocks other content in a zoomed area. It ensures that the additional content is dismissible with the keyboard without moving focus/hover.
Character Key Shortcuts (A): This criterion was added to prevent accidental activation of shortcut keys. When key shortcuts are used without modifiers or a turn-off mechanism, speech users could accidentally activate shortcuts while navigating a page.
Label in Name (A): The aria-label or the coded name for a text should include the content of its visual text label. When the computed name does not match the visible text label, users will not be able to access that control. For example, if you have an input with the visible text label as “Click here”, but the aria-label or the alt-text says, “Click this button”, this success criterion would fail.
Animation from Interactions (AAA): Users should be able to disable the motion animation triggered by user-interaction on screen.
Pointer Gestures (A): This criterion is of benefit to users who lack the accuracy, dexterity, or tools to perform complex gestures with precision. It ensures that functionality on a page is operated using a single pointer.
Pointer Cancellation (A): It prevents mouse interaction from occurring when pressing or when releasing the mouse button, thus accidentally triggering touch or mouse events with unwanted results.
Motion Actuation (A): When device motion or user motion such as shaking, tilting etc., are used for interaction, an alternative input method should be provided to perform an equivalent action, otherwise, users with motor impairments would be unable to access the functionality on the page.
Target Size (AAA): The target size for pointer input should be at least 44×44 CSS pixels to improve usability for people with hand tremors, limited dexterity or other limitations.
Concurrent Input Mechanisms (AAA): This criterion ensures that the authors don’t actively disable input modalities and therefore interfere with the way users are accessing content.
Orientation (Level AA): Web content should be operable in either orientation, that is, portrait or landscape. This criterion is useful for users with low vision who may change the orientation of a device to increase the width of the reading area or increase the size of content.
Status Messages (AA): When an action is performed on screen that does not change focus, users must be notified of it with a status message or an announcement.
The world wide web is for everyone, irrespective of their abilities and disabilities.
