As leading experts in web content accessibility, it’s not uncommon people ask us “what is WCAG?”. If you found yourself wondering the same question or wondering how to improve your web content accessibility, this blog post is for you.
What is WCAG?
At its core, the Web Content Accessibility Guidelines (WCAG) is dedicated to inclusivity. Essentially, WCAG is a set of global guidelines for making digital spaces accessible to everyone. Making websites and web content accessible to all ensures everyone can enjoy online knowledge and experiences. Plus, it can help organisations reach a more diverse audience.
A common misconception is when accessibility is prioritised, it might compromise design. However, the opposite is true - it enhances user experience (UX). We’ll cover more on this shortly.
Why does WCAG exist?
Web Content Accessibility Guidelines were first released in 1999(external link). Since then, it's received a few updates to keep pace with technology and address new challenges.
Essentially WCAG serves as a worldwide tool in narrowing the digital gap for people with disabilities. The purpose is to ensure websites and digital platforms accommodate a range of impairments. For example, visual, auditory, cognitive, and motor limitations. When website owners, developers, and content creators meet the guideline standards, they create an inclusive online experience. However, it's important to recognise accessibility extends beyond the end-user experience. Additionally, platform backends should ensure they support a diverse workforce.
Who does WCAG apply to?
- WCAG applies to everyone who creates and maintains digital content.(external link) For example, everyone involved in web development, design, content creation, and business ownership.
- All public sector organisations in New Zealand(external link) must show they are improving web accessibility for everyone.
- For private sector organisations, the guidelines are not mandated but offered as a best practice. However, improving accessibility makes the overall user experience better for everyone. Also, it helps your organisation reach and attract a wider range of people.
The main point is that accessibility shouldn't be done just to check a box or only for business growth. In fact, being able to access content regardless of ability level is a human right.(external link)
The Four Principles of WCAG
The Web Content Accessibility Guidelines are based on four key principles(external link) covering important aspects of digital accessibility. The four principles of WCAG are:
- Perceivable: Information and user interface components must be presented in a way that users can understand. This should cater to different sensory abilities.
- Operable: The user interface and navigation should be easy to use and navigate. This will help people interact with and move around in the digital space.
- Understandable: The user interface should be easy to understand, promoting clarity and ease of use.
- Robust: The content needs to work well with different devices and tools that help people. It should also keep up with new technology.
