Content Everyone Can Perceive.
Interfaces Everyone Can Operate.
Standards You Can Prove.
The Web Content Accessibility Guidelines (WCAG) are the technical foundation behind nearly every digital accessibility law in the world. We help you test against WCAG 2.1/2.2 AA and turn every finding into a working fix.
What is WCAG?
The Web Content Accessibility Guidelines (WCAG) are a set of internationally recognized technical standards published by the World Wide Web Consortium (W3C), written to make websites, apps, and digital documents usable by people with visual, auditory, motor, and cognitive disabilities. WCAG isn't itself a law - it's the technical benchmark that most accessibility laws point to when they say a site must be "accessible."
At D2i Technology, we test against WCAG using a mix of automated scanning and hands-on manual review with screen readers, keyboard-only navigation, and other assistive technology - because automated tools alone typically catch only a fraction of real-world accessibility issues.
WCAG conformance at Level AA is now the de facto benchmark cited by the ADA, Section 508, the European Accessibility Act, Canada's accessibility laws, and India's RPwD Act - which means a single, well-executed WCAG program covers most of your legal exposure at once.
WCAG Essentials
The 4 Principles of WCAG
Every WCAG success criterion falls under one of four principles - remembered by the acronym POUR
Perceivable
Information and interface elements must be presentable in ways users can perceive - alt text for images, captions for video, and content that isn't conveyed by color alone.
Operable
All functionality must work from a keyboard, with no time limits users can't control and no content that triggers seizures or physical reactions.
Understandable
Text must be readable, pages must behave predictably, and forms should help users avoid and correct mistakes.
Robust
Content must be coded to work reliably across current and future browsers, devices, and assistive technologies such as screen readers.
WCAG Levels of Conformance
WCAG defines three progressively stricter levels of conformance
Level A
The baseline. Covers the most severe barriers, such as content that's completely unusable without sight or a mouse.
- Every image has alternative text
- No content flashes more than 3 times per second
- Page has a clear, programmatic title
Level AA
The benchmark cited by virtually every accessibility law worldwide, and what we recommend and test to by default.
- Text contrast of at least 4.5:1
- Content resizes to 200% without loss of function
- Consistent navigation and labeling across pages
Level AAA
The highest standard. Rarely required in full across an entire site, but often targeted for specific critical flows.
- Text contrast of at least 7:1
- Sign language interpretation for pre-recorded audio
- No timing requirements for reading or interaction
How WCAG Has Evolved Over Time
Each new version adds success criteria on top of the last - nothing from an earlier version is removed
WCAG 2.0
2008The foundation of modern accessibility guidelines. Introduced the four POUR principles and remains the baseline that older laws like Section 508 still reference directly.
WCAG 2.1
2018Extended coverage to mobile devices, low-vision users, and people with cognitive and learning disabilities, without removing any 2.0 criteria.
WCAG 2.2
2023The current stable version. Adds criteria for visible focus, larger touch targets, and easier authentication that doesn't rely on memory alone.
Looking ahead - WCAG 3.0: currently a W3C Working Draft, WCAG 3.0 proposes replacing pass/fail success criteria with a broader Bronze/Silver/Gold scoring model. It isn't finalized and isn't required by any law today - WCAG 2.1/2.2 AA remains the standard to build for now, and we track WCAG 3.0's progress so your program stays ready when it lands.
