The Future of Web Accessibility: Unpacking WCAG 3.0, APCA, and the Role of Design Tools

4 min read • Eugenia Sorgetti

In an increasingly digital world, ensuring web accessibility for everyone, including people with disabilities, is of utmost importance. Web accessibility ensures that all users can perceive, understand, navigate, interact with, and contribute to the web. The Web Content Accessibility Guidelines (WCAG), developed by the World Wide Web Consortium (W3C), provides a robust framework for creating accessible web content. These guidelines ensure that businesses are not inadvertently excluding potential customers, and they contribute to a more inclusive digital space. This blog post aims to delve into the evolution of WCAG, discuss its different versions, the Advanced Perceptual Contrast Algorithm (APCA), and even explore how design tools like Figma plugins aid in achieving superior web accessibility.

Understanding Web Content Accessibility Guidelines (WCAG)

The Genesis and Evolution of WCAG

WCAG was initiated by the W3C to establish a standard for web accessibility. The initial version, WCAG 1.0, launched in 1999, aimed to make the web accessible to people with disabilities, providing them with an inclusive web experience.

WCAG 2.0 Vs. WCAG 2.1: What Changed?

Building on the groundwork of 1.0, WCAG 2.0 was launched in 2008 to address technological advancements and provide clearer, technology-neutral guidelines. Subsequently, WCAG 2.1, introduced in 2018, incorporated additional success criteria to cater for mobile accessibility, people with low vision, and people with cognitive and learning disabilities.

WCAG’s Role in Enhancing Accessibility

WCAG's primary role is to guide organizations in making their web content more accessible. By following these guidelines, businesses can ensure that their digital platforms are more usable for people with varying abilities, promoting digital inclusion. In the following sections, we will explore the depth of these guidelines, including different conformance levels, the new WCAG 3.0 draft, and the future of web accessibility.

Designers should always keep their users in mind

The Shift Towards WCAG 3.0 and Advanced Perceptual Contrast Algorithm (APCA)

As we look towards the future of web accessibility, two significant advancements stand out: the draft of WCAG 3.0 and the Advanced Perceptual Contrast Algorithm (APCA). These innovations are poised to dramatically enhance the way we approach and implement web accessibility, although both are still in stages of testing, revision, and peer review. For now, it is safer for organizations to adhere to WCAG 2.1 AA as a baseline for accessibility standards.

Introduction to WCAG 3.0

In 2020, the W3C introduced the first draft of WCAG 3.0, representing a substantial departure from the previous version. WCAG 3.0, also known as the Silver Project, aims to make the guidelines more user-friendly, and comprehensive, with a more holistic approach to accessibility.

One of the major shifts in WCAG 3.0 is the focus on user needs rather than technology-specific solutions, as well as an emphasis on functional outcomes instead of prescriptive methods. Additionally, the new guidelines aim to provide a more flexible framework to accommodate emerging technologies and varied methods of web interaction. It also introduces new grading levels to offer a wider range of conformance options.

However, it's crucial to remember that WCAG 3.0 is still a draft. It's undergoing rigorous testing, refinement, and peer review before it can be adopted as the new standard for web accessibility.

Embracing Advanced Perceptual Contrast Algorithm (APCA)

Alongside the development of WCAG 3.0, another significant advancement in web accessibility is the introduction of the Advanced Perceptual Contrast Algorithm (APCA). The APCA is a new way of measuring contrast between web elements that promises to offer a more nuanced and accurate analysis compared to the current contrast ratio requirements under WCAG 2.1.

WCAG 2 and APCA comparison

The APCA takes into consideration factors such as text size, font weight, and ambient light, which are not considered in the current contrast ratio model. This provides a more accurate and realistic assessment of how various design elements and colors would appear to different users, including those with visual impairments.

However, like WCAG 3.0, APCA is also in the testing and review phase. While promising, it's crucial to remember that the APCA is still being refined and has yet to be formally adopted as a standard for web accessibility.

In conclusion, while WCAG 3.0 and APCA represent significant leaps forward in the evolution of web accessibility, organizations should continue to adhere to the established WCAG 2.1 AA guidelines until these new standards have been thoroughly vetted, tested, and accepted by the wider community.

Tools and Resources for Implementing Web Accessibility

In addition to understanding the WCAG guidelines, it's vital to leverage tools that can aid in the practical application of these standards. There are numerous tools available for checking web accessibility, including WAVE and AXE. These resources evaluate your website or web application and provide insights into how well it meets accessibility standards.

One tool that has gained significant traction is Figma, a versatile design platform that also offers plugins for designing accessible web content. These plugins can automate many aspects of accessibility design, saving designers significant time and effort. Here are a few blog entries that provide in-depth exploration of Figma and its functionalities:

Conclusion and Further Reading

Web accessibility is an essential aspect of modern digital platforms, contributing to a more inclusive and user-friendly web experience. Adhering to WCAG guidelines and utilizing the right design tools can significantly enhance the accessibility of your website or application. While innovations like WCAG 3.0 and APCA are promising, WCAG 2.1 remains the reliable baseline for current web accessibility standards.

We encourage readers to explore the detailed entries about Figma and its use for enhancing web accessibility mentioned above.
