Accessibility

What this skill does

This skill provides a comprehensive overview of implementing web accessibility based on WCAG 2.2 guidelines, focusing primarily on achieving Level AA conformance. It emphasizes using native HTML elements to leverage built-in accessibility features rather than relying on ARIA roles unnecessarily. The skill covers semantic HTML structure, proper heading hierarchy, keyboard navigation support, and appropriate ARIA usage patterns to ensure content is accessible to users with disabilities. It also highlights practical considerations like minimum target size for interactive elements and focus management in dynamic UI components such as modals and tabs.

Who it's for

This skill is designed for performance marketers optimizing landing pages and conversion funnels to meet accessibility standards without sacrificing user experience. Growth leads responsible for compliance with ADA or EN 301 549 regulations will find this skill essential to balance legal requirements and usability. SEO and PPC operators aiming to improve site quality signals and reduce bounce rates through accessible design will benefit, as well as agency strategists advising clients on inclusive web design that supports broader audience reach.

Key workflows

Practitioners begin by auditing existing page markup to replace non-semantic `<div>` elements with native HTML tags like `<nav>`, `<main>`, and `<button>`, which provide built-in accessibility advantages. Next, they verify heading hierarchy to ensure only one `<h1>` per page and avoid skipping levels, enabling screen readers to construct meaningful page outlines. The third step involves testing keyboard navigation and focus management, adding skip links and trapping focus within modals to support users who rely on keyboards exclusively. Finally, they apply ARIA roles and attributes only when native elements cannot achieve the required semantics, following strict rules to avoid redundant or conflicting markup.

Common questions

How strictly must I adhere to WCAG levels? Level AA compliance is the practical industry standard and legal requirement in many jurisdictions, while AAA is aspirational and often infeasible for full sites. Can ARIA replace native HTML elements? No, ARIA should never substitute native semantics but only augment non-semantic elements when necessary. What’s the best way to test keyboard accessibility? Use keyboard-only navigation to verify tab order follows logical DOM sequence, focus is visible, and interactive elements respond to standard keys like Space and Enter.

How to use in Metaflow

Attach the Accessibility skill to any Metaflow agent tasked with content or frontend evaluation to automatically analyze markup semantics, heading structure, and keyboard navigation patterns. The skill will flag common accessibility issues and recommend native HTML replacements or ARIA adjustments aligned with WCAG 2.2 AA standards. Expect actionable insights that help you prioritize fixes for legal compliance and improved user experience across devices and assistive technologies. This skill integrates smoothly into workflows for continuous accessibility monitoring and remediation.
