Mobile Keyboard & Autofill
Action
1/2 eligible field(s) missing autocomplete or inputmode
REVIEW
1/2 eligible field(s) missing autocomplete or inputmode
Warning::
1 field(s) would benefit from inputmode attribute
Mobile browsers pick the on-screen keyboard layout from `inputmode=` when present (numeric pad, tel dialpad, email keyboard). Without it, users see the default text keyboard and must mode-switch -- 2-3 extra taps per phone-number or numeric-ID field. Type-based defaults exist (`type=tel` shows the tel keyboard on most browsers) but `inputmode` is the explicit, cross-browser way to control this. Affected types: email.
Got: <input type="email">
B
Mobile-Readable Font Sizes
97% of visible text renders at >= 12 CSS px (3 below threshold)
REVIEW
97% of visible text renders at >= 12 CSS px (3 below threshold)
Info::
3 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> 10.0px ("Pet"); <span> 10.0px ("Portrait"); <span> 10.0px ("Product").

Warning::
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
BANNER header NAV "Navigation" MAIN CONTENTINFO footer

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.

Manifest has no maskable icon
Android 12+ Adaptive Icons crop non-maskable icons to a circle or squircle -- frequently hiding important parts of the logo. Add at least one icon entry with `"purpose": "maskable"` (or `"any maskable"`) and a maskable-aware design (16% safe-zone padding around the inner mark).

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.

Visible text labels that do not match the accessible name can result in a confusing experience for screen reader users. Learn more about accessible names.

Why this matters

Performance issues directly impact user engagement and conversion rates.
