Ensure your product is usable by everyone. This checklist covers the essentials for meeting WCAG 2.1 AA standards.
Text has a contrast ratio of at least 4.5:1 against its background (3:1 for large text).
Color is not used as the only visual means of conveying information (e.g., use icons or text for errors).
Text can be resized up to 200% without loss of content or functionality.
All interactive elements can be accessed and operated using only a keyboard (Tab, Enter, Space, Arrows).
The keyboard focus indicator is clearly visible on all interactive elements.
Focus is not trapped in any component; users can tab in and out of everything.
Headings (h1-h6) are used correctly to convey the document structure, not just for styling.
All meaningful images have descriptive alt text. Decorative images have empty alt attributes (alt="").
Form fields have clear, visible labels. Instructions are provided when content requires user input.
