Accessibility Audit

Comprehensive WCAG 2.1 accessibility audit for Webflow pages with detailed issue detection and actionable fixes.

Important Note

ALWAYS use Webflow MCP tools for all operations:

Use Webflow MCP's webflow_guide_tool to get best practices before starting Use Webflow MCP's data_sites_tool with action list_sites to identify available sites Use Webflow MCP's data_sites_tool with action get_site to retrieve site details Use Webflow MCP's data_pages_tool with action list_pages to get all pages Use Webflow MCP's element_tool with action get_all_elements to get detailed element information (requires Designer) Use Webflow MCP's element_tool with action add_or_update_attribute to fix accessibility issues (requires Designer) Use Webflow MCP's element_snapshot_tool to get visual previews of elements DO NOT use any other tools or methods for Webflow operations All tool calls must include the required context parameter (15-25 words, third-person perspective) Designer connection required - This skill needs Designer to access element attributes and styles Instructions Phase 1: Site & Page Selection Get site information: Use Webflow MCP's data_sites_tool with action list_sites to identify target site Ask for page selection: If user provides page ID, use it directly Otherwise, use data_pages_tool with action list_pages to show available pages Let user select which page(s) to audit Confirm audit scope: Ask user what to check: Full audit (all accessibility checks) Critical issues only (WCAG Level A) Specific categories (forms, buttons, navigation, etc.) Phase 2: Element Extraction & Analysis Ensure Designer is connected: Before proceeding, verify Webflow Designer is open and connected If not connected, instruct user to open Designer and connect This is required to access element attributes and styles Switch to target page: Use de_page_tool with action switch_page to navigate to the page being audited Extract all elements: Use element_tool with action get_all_elements for detailed analysis Set include_style_properties: true to check focus styles Set include_all_breakpoint_styles: false to minimize data Parse element data: Identify interactive and content elements: Buttons (Button, LinkBlock with button role) Links (TextLink, Link, LinkBlock) Form inputs (Input, Select, Textarea) Headings (Heading elements with levels) Interactive divs/spans (check for onClick or interactive roles) Images (Image elements) - SKIP for this audit Extract attributes for each element: ARIA attributes (aria-label, aria-describedby, role, tabIndex) DOM attributes (id, domId, href, type, placeholder) Text content Style properties (outline, border for focus states) Element metadata (canHaveAttributes, tag name) Phase 3: Accessibility Checks Critical Issues (Must Fix - WCAG Level A)

Icon-only buttons without labels (WCAG 4.1.2)

Find: Button elements with no text content Check: Missing aria-label or aria-labelledby Impact: Screen readers cannot identify button purpose Fix: Add aria-label attribute with descriptive text

Form inputs without labels (WCAG 1.3.1)

Find: Input, Select, Textarea elements Check: Missing associated label or aria-label Impact: Users don't know what input is for Fix: Add aria-label or associate with using id

Non-semantic click handlers (WCAG 2.1.1)

Find: Div or Span elements (identified by element type) Check: Interactive behavior without proper role/keyboard support Impact: Not keyboard accessible, screen readers miss interactivity Fix: Add role="button", tabIndex="0", suggest using real

Links without destination (WCAG 2.1.1)

Find: Link elements with no href attribute Check: Links that only use onClick without href Impact: Not keyboard accessible, breaks browser features Fix: Add proper href or convert to button Serious Issues (Should Fix - WCAG Level AA)

Focus outline removed without replacement (WCAG 2.4.7)

Find: Elements with outline: none style Check: No visible alternative focus indicator Impact: Keyboard users can't see focus Fix: Add visible focus style (border, box-shadow, background change)

Missing keyboard handlers (WCAG 2.1.1)

Find: Elements with onClick handlers Check: Missing onKeyDown for Enter/Space keys Impact: Not usable with keyboard alone Fix: Add keyboard event handlers

Touch target too small (WCAG 2.5.5)

Find: Clickable elements (buttons, links) Check: Width or height < 44px Impact: Hard to tap on mobile devices Fix: Increase padding or min-width/min-height to 44px Moderate Issues (Consider Fixing)

Heading hierarchy problems (WCAG 1.3.1)

Find: Heading elements (h1-h6) Check: Skipped levels (h1 → h3, skipping h2) Impact: Confusing document structure Fix: Use proper sequential heading levels

Positive tabIndex (WCAG 2.4.3)

Find: Elements with tabIndex > 0 Check: Disrupts natural tab order Impact: Confusing keyboard navigation Fix: Use tabIndex="0" or "-1" only, let natural DOM order work

Role without required attributes (WCAG 4.1.2)

Find: Elements with ARIA roles Check: Missing required ARIA attributes (e.g., role="button" without tabIndex) Impact: Incomplete accessibility semantics Fix: Add required attributes for role Phase 4: Issue Categorization & Scoring

Categorize all findings:

Critical: Must fix (blocks access) Serious: Should fix (significantly impacts usability) Moderate: Consider fixing (improves experience)

Calculate accessibility score (0-100):

Start at 100 Critical issue: -10 points each Serious issue: -5 points each Moderate issue: -2 points each Minimum score: 0

Generate severity summary:

WCAG 2.1 quick reference links Webflow accessibility best practices Recommended testing tools (browser extensions, screen readers) Important Considerations What This Skill Checks

✅ Button accessibility (labels, roles) ✅ Form input labels and associations ✅ Link semantics and keyboard access ✅ Focus visibility and keyboard navigation ✅ Heading hierarchy and structure ✅ ARIA roles and attributes ✅ Touch target sizes ✅ Interactive element semantics

What This Skill Does NOT Check

❌ Image alt text (use asset-audit skill instead) ❌ Color contrast ratios (requires visual analysis) ❌ Animation/motion preferences ❌ Screen reader testing (needs manual verification) ❌ Content readability (language level, clarity)

Limitations Cannot detect visual-only issues (color contrast, small text) Cannot test actual screen reader behavior Cannot validate content quality or clarity Relies on element attributes and structure only Examples Example 1: Full Page Audit
