Importance of WCAG standards

While WCAG was created for web accessibility, it's highly relevant for mobile. Despite differences, many devices now share features—touchscreens on laptops, keyboards with mobile devices—making the gap smaller than expected.

Since many UI components appear across platforms, WCAG 2.1 guidelines apply to both web and non-web interfaces.^[1]

WCAG's four core principles help organize accessibility requirements:

• Perceivable: Content must be accessible and processable through various assistive technologies
• Operable: Key features should work through multiple methods. For example, users should be able to input text not only with a keyboard but also by using voice recognition tools like speech-to-text.
• Understandable: Users must comprehend content and tasks through clear labels and instructions
• Robust: Systems should support various platforms and assistive technologies used by the target audience
