Sample Diagnostic Violations & Fixes

Critical Impact (-20 pts) WCAG 1.4.3 Contrast (Minimum)
color-contrast: Elements must have sufficient color contrast
<button class="btn-submit" style="background: #a5b4fc; color: #ffffff;">Complete Purchase</button>
💡 Fix Guidance: Contrast ratio is 2.8:1 (minimum 4.5:1 required). Change background color to #4f46e5 or text color to #1e1b4b.
Serious Impact (-10 pts) WCAG 1.1.1 Non-text Content
image-alt: Images must have alternate text for screen readers
<img src="/assets/hero-banner.jpg" class="hero-img">
💡 Fix Guidance: Add a descriptive alt attribute (e.g. alt="Summer sale promotion 20% off") or alt="" if purely decorative.

📊

Penalty-Based Accessibility Score (0–100 & Grade A–F)

A fast, impact-weighted grading scale that penalizes high-severity accessibility barriers. Perfect for leadership updates and clear progress tracking.

  • Deducts points based on user impact: Critical (-20), Serious (-10), Moderate (-5), Minor (-2)
  • Generates instant letter grades (A ≥ 90, B ≥ 75, C ≥ 40, D ≥ 25, F < 25)
  • Prevents severe critical violations from hiding behind high pass percentages
⚖️

  • Calculates exact failure rate per WCAG Success Criterion
  • Directly maps to legal audit requirements and VPAT / ACR documentation
  • Provides granular success criterion breakdown across 43 WCAG 2.1 A/AA criteria
