Landmark Structure

Action

No landmarks

FIX

No landmarks

No <main> landmark found

Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.

No <nav> landmark found

No banner (header) landmark

No contentinfo (footer) landmark

Skip navigation link is missing (WCAG 2.4.1)

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

No landmarks detected

Screen reader users have no way to navigate by region.

Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.

Why this matters

Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.

Learn more ▾

The <main> element marks the page's primary content area. Assistive tech offers a 'jump to main' shortcut — but only if <main> exists. Without it, every page navigation forces re-reading the header. Wrap your primary content in a single <main>.

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

Why this matters

Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.

Learn more ▾

WCAG 2.4.1 (Bypass Blocks) requires a mechanism to skip past repeated content. The standard implementation is a 'Skip to main content' link that's the first focusable element, visually hidden until focused. Three lines of HTML + four of CSS.

404 Error Page

Action

HTTP 404, bare page

FIX

HTTP 404, bare page

Correct 404 status code returned

Got: HTTP 404

Bare server default 404 page

The 404 page has no custom styling. Users hitting a broken link see a generic error with no way to navigate back. Add a custom 404 page with your site navigation and a search bar.

Favicon & Branding

Action

FIX

2 icon(s) detected

favicon.ico present at site root

Web Manifest

Action

Not found

FIX

Not found

No web manifest found

No manifest at standard paths (/manifest.json, /site.webmanifest). A manifest is optional but enables PWA features like home screen installation and standalone display.

No web manifest found.

Dark Mode Support

Action

No dark mode signals

FIX

No dark mode signals

No dark mode signals detected

Consider adding CSS with @media (prefers-color-scheme: dark) and <meta name='color-scheme' content='light dark'>.

Detection limited to meta tags and inline styles

External CSS files may contain prefers-color-scheme rules not visible to this scan.

Print Stylesheet

Action

No print styles

FIX

No print styles

No print-specific styles detected

When users print this page, they get the screen layout including navigation and non-essential elements. Add @media print rules to hide navigation and optimize layout for paper.

Form Accessibility

2 of 9 controls have issues

REVIEW

2 of 9 controls have issues

2 control(s) without accessible label

Form controls need a <label>, aria-label, or aria-labelledby for screen readers.

Got: <input type="number" name="price">; <select id="donate-contribute-currency">

7 control(s) properly labeled

9 controls

7 labeled

0 placeholder only

Form controls need a <label>, aria-label, or aria-labelledby for screen readers.

Why this matters

Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.
