A look back at WCAG 2.0
Let’s take a quick look back on the Website Compliance Accessibility Guidelines 2.0 (WCAG), established in 2008. The WCAG guidelines are a specific set of standards designed to make the web more accessible to people with disabilities. They remain the gold standard in 2020, with some new additions for our ever-evolving technologies. WCAG 2.0 was founded on four principles that remain at the core of the guidelines:
- Perceivable usability - Website information and components must be presented to users in ways they can easily perceive.
- Operable usability - Website components and navigation must allow users to operate the website with ease.
- Understandable information and operational updates - Information and the operation of the website must be understandable. Users must be able to understand the information, as well as how to navigate through it.
- Robust content - Content must be robust enough that it can be interpreted reliably by a wide variety of software, including assistive technology tools. Users must be able to access the content as technologies advance, no matter which device they choose.
Compliance within each of these four categories may require updates to your website. These updates may range from incorporating simple text alternatives that you can implement in a matter of minutes to larger updates that will require partnering with your development team. To meet the needs of different groups and different situations, the three levels of conformance are defined as: A (lowest), AA, and AAA (highest).
