AI-Powered
Our AI analyzes your page's spacing, typography, colors, and accessibility — returning a detailed report with exact CSS fixes you can apply immediately.
The page has critical accessibility violations including 5 images missing alt attributes and a broken heading hierarchy (h1 jumps directly to h3 before any h2 appears). Typography is largely consistent but the h2 elements use two different font sizes (40px vs 48px), which looks unpolished.
Five <img> elements have no alt attribute at all. This fails WCAG 2.1 Success Criterion 1.1.1 (Non-text Content, Level A). Screen readers will either skip these images or announce the filename/URL, creating a broken experience for assistive technology users.
The heading order starts at h1, then immediately uses h3 elements before any h2 appears in the DOM. This violates WCAG 2.1 SC 1.3.1 (Info and Relationships) and SC 2.4.6 (Headings and Labels).
