accessibility-perceivable

To audit UI for WCAG Perceivable compliance, evaluate text alternatives for non-text content, verify time-based media captions and transcripts, check semantic structure adaptability, and measure color contrast ratios to identify specific accessibility failures.

WCAG requirements for text alternatives and contrast mandate providing alt text for images and icons, ensuring measurable contrast ratios for distinguishable presentation, and supplying captions or transcripts for time-based media so content is perceivable by users with visual or auditory constraints.

Adding captions and transcripts to media-rich landing pages involves providing synchronized text alternatives for time-based media, implementing controls for autoplay audio, and including audio descriptions to satisfy accessibility audits for users with auditory perception constraints.

You can use semantic markup to fix adaptable structure issues by establishing meaningful programmatic relationships between elements, which corrects reading order and ensures content reflows properly for users relying on assistive technologies during accessibility audits.

This accessibility audit handles reflow and non-color cues for dashboards with charts by verifying resizing support, enforcing distinguishable presentation through non-color reliant indicators, and testing semantic relationships within complex visual data structures.
