Applying Web Content Accessibility Guidelines (WCAG)
What Are the Web Content Accessibility Guidelines (WCAG)?
Before diving into the details of the versions, updates, and how to apply these guidelines to websites, it's essential to understand WCAG: the Web Content Accessibility Guidelines. Created by the World Wide Web Consortium (W3C), founded by Tim Berners-Lee, the inventor of the internet, these guidelines aim to make web content accessible, focusing on the rights of individuals with disabilities, those with various impairments, and elderly. WCAG addresses a range of accessibility needs, from physical, cognitive, sensory, and neurological disabilities to age-related challenges, and includes best practices for improving usability and focus during reading and browsing.
Versions of the Guidelines: Enhancements and Additions
The WCAG guidelines have seen few updates, considering their over 30-year history, reflecting the major stages of internet evolution from its inception to today's advancements (as of 2024). Here is a timeline of WCAG versions:
- WCAG 1.0 (1999)
- WCAG 2.0 (2008)
- WCAG 2.1 (2018)
- WCAG 2.2 (2023)
The third version introduced 17 new success criteria, while the latest update, WCAG 2.2, added guidelines specific to mobile accessibility and catered to individuals with cognitive and learning difficulties, as well as those with low vision. WCAG 2.0 and 2.1 remain the most widely referenced in international laws and regulations. The latest update from October 2023 was built on key principles of accessible web design, helping developers create comprehensive content for those with visual, auditory, physical, and cognitive impairments. Work on WCAG 3.0 is already underway to keep advancing accessibility.
How to Make a Website WCAG Compliant?
Compliance Levels
WCAG defines three levels of compliance, each building upon the previous with additional criteria that enhance user experience:
Level A: This basic level removes significant barriers, such as including alt text for images to ensure that screen readers can fully interpret visual content, especially vital for users with visual impairments.
Level AA: Extending the basics, this intermediate level incorporates features like audio descriptions for videos, enhancing accessibility for those with vision impairments.
Level AAA: The highest level ensures a comprehensive experience, including detailed audio descriptions for images and sign language interpretation, offering an all-encompassing, seamless user experience.
Core Principles of WCAG
The guidelines are structured around four foundational principles, each encompassing specific, measurable objectives:
Perceivable: Ensures that users can perceive content, making it accessible via at least one sensory channel. This principle includes standards for alternative text for images, synchronized text captions for videos, flexible content scaling, and clear formatting.
Operable: Enables users to navigate and interact with the website, with standards such as full keyboard accessibility, enough time for content, seizure-safe design, intuitive navigation, and multiple input methods.
Understandable: Ensures users can comprehend and interact meaningfully with information, including standards for readable content, predictable navigation, and input assistance.
Robust: Ensures content accessibility across evolving technologies, aiming for compatibility with assistive tech and adaptive software.
