Mobile Keyboard & Autofill

1/4 eligible field(s) missing autocomplete or inputmode

REVIEW

1/4 eligible field(s) missing autocomplete or inputmode

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" name="email" id="email">

Mobile-Readable Font Sizes

90% of visible text renders at >= 12 CSS px (14 below threshold)

REVIEW

90% of visible text renders at >= 12 CSS px (14 below threshold)

14 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: <h3> 11.0px ("Infrastruttura e Virtualizzazione"); <h3> 11.0px ("Rete e Sicurezza Perimetrale"); <h3> 11.0px ("Vulnerability Assessment"); <span> 11.0px ("profit"); <span> 11.0px ("profit").

Methodology: The top 20 text elements by font size were checked. Background color was sampled from the desktop screenshot using a 5-point pattern. WCAG 2.1 AA requires 4.5:1 for normal text and 3:1 for large text.

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.

Heading Text Quality

1 heading-text-quality issue(s) detected

PASS

1 heading-text-quality issue(s) detected

1 heading(s) are all-uppercase (excluding short acronyms)

Headings rendered in all-uppercase are a styling choice that should be done via CSS (`text-transform: uppercase`), not by typing the text in caps. Capitalized text is read letter-by-letter by some screen readers (e.g., "H-E-L-L-O W-O-R-L-D" instead of "hello world"). It's also a soft signal of CMS-migration artifacts where the original lowercase intent was lost.

Got: 1 all-caps heading(s)

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

0 positive, 1 -1-on-focusable

tabindex="-1" on naturally-focusable <input id="hp-check">

tabindex="-1" removes an element from the keyboard tab order. Naturally-focusable elements (links, buttons, form controls) become unreachable for keyboard users. (Common false-positive: hidden honeypot fields. Verify the element is genuinely interactive before removing the tabindex.)

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.
