# WCAG (Web Content Accessibility Guidelines)
## Overview
The Web Content Accessibility Guidelines (WCAG) are international standards published by the World Wide Web Consortium's (W3C) Web Accessibility Initiative (WAI), defining how to make web content accessible to people with disabilities. WCAG ensures that people with visual, auditory, motor, cognitive, and neurological disabilities can perceive, operate, understand, and interact with digital content.
The guidelines are organized around four foundational principles known as POUR: Perceivable (information presented in ways all users can perceive), Operable (interface usable by all), Understandable (clear information and operation), and Robust (compatible with assistive technologies). WCAG defines three conformance levels: A (minimum), AA (target for most organizations), and AAA (highest). The current version is WCAG 2.2 (October 2023), with 13 guidelines and specific testable success criteria.
## When to Use
- Designing or developing any web content, application, or digital product
- Legal compliance required (ADA, Section 508, EU Accessibility Act)
- Expanding audience reach (1 in 4 adults has a disability in the US)
- Building products for government, education, or healthcare sectors
- Conducting accessibility audits or QA testing
- Onboarding designers/developers to accessibility standards
- Evaluating third-party components or libraries for accessibility
## The Process
### Step 1: Perceivable - Information Presentable to All Users
Ensure all information and UI components can be perceived through multiple senses (not sight alone).

- Provide alt text for images: ``
- Captions for videos, transcripts for audio
**Adaptable Content (1.3):**
- Use semantic HTML: `
