Form Accessibility

Action

REVIEW

5 of 6 controls have issues

5 control(s) without accessible label

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

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.

Mobile-Readable Font Sizes

Action

84% of visible text renders at >= 12 CSS px (25 below threshold)

REVIEW

84% of visible text renders at >= 12 CSS px (25 below threshold)

25 text node(s) render below 12 CSS pixels on mobile

Mobile browsers default the root font-size to 16 px; text below ~ 12 px (75% of root) is hard to read without zooming. WCAG 1.4.4 (Resize Text) requires the page to support 200% zoom without loss of functionality -- which most layouts handle, but small base text still costs readability and conversion. Audit which selectors set sizes below 12 px (often footers, fine print, table cells) and bump them to 14-16 px or use rem units that scale with user preferences. Examples: <span> 9.0px ("20% ANNUAL SAVINGS"); <a> 11.0px ("Explore Annual Plans"); <span> 10.0px ("20% OFF"); <span> 10.0px ("EN"); <span> 11.0px ("English").

Landmark Structure

PASS

7 landmarks

<main> landmark present

2 <nav> landmark(s) found

All <nav> elements are properly labeled

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.

Page Structure — as a screen reader sees it

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.

Why this matters

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.

PASS

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.

Why this matters

Performance issues directly impact user engagement and conversion rates.
