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 <label> 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 <button>
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 â 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:
- Total issues found
- Breakdown by severity
- Most common issue types
- Pages/sections most affected

Phase 5: Report Generation

Important Considerations

What This Skill Checks

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

What This Skill Does NOT Check

â Image alt text (use asset-audit skill instead) â Color contrast ratios (requires visual analysis) â Animation/motion preferences â Screen reader testing (needs manual verification) â 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
