CLandmark StructureAction5 landmarksREVIEW
Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.
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.
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.

CForm AccessibilityAction3 of 5 controls have issuesREVIEW
| Control | Type | Label | Method |
|---|---|---|---|
| #languages-site-header-input | text | Language: | for/id |
| #languages-site-footer-input | text | Language: | for/id |
| #searchInput | search | (none) | none |
| #languages-site-footer-fallback-nav | select | (none) | none |
| #languages-site-header-fallback-nav | select | (none) | none |
Form controls need a <label>, aria-label, or aria-labelledby for screen readers.
<select id="languages-site-header-fallback-nav">; <input type="search" id="searchInput">; <select id="languages-site-footer-fallback-nav">
Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.

Accessibility
These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.
Contrast
Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.
Performance issues directly impact user engagement and conversion rates.

Links with target="_blank" without rel="noopener" leak the originating page's window context — security and UX issue.
Learn more ▾ ▴
Without rel="noopener", the new tab can navigate the original tab via window.opener (tab-nabbing attack). Modern browsers default to noopener for target=_blank but only since recent versions. Always set rel="noopener noreferrer" explicitly.
