No web manifest found.

Dark Mode Support

Action

Theme color only

FIX

Theme color only

Theme-color present but no dark variant

A theme-color is set but no dark-specific variant was found. The browser toolbar may not adapt for dark mode users.

Got: #0a0e1a

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

Mobile Keyboard & Autofill

Action

1/3 eligible field(s) missing autocomplete or inputmode

REVIEW

1/3 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">

Mobile-Readable Font Sizes

Action

77% of visible text renders at >= 12 CSS px (67 below threshold)

REVIEW

77% of visible text renders at >= 12 CSS px (67 below threshold)

67 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: <small> 9.0px ("Software Architect"); <p> 11.5px ("À propos"); <span> 11.5px ("ans exp."); <span> 11.5px ("projets"); <span> 11.5px ("Recherche").

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.

Landmark Structure

12 landmarks

PASS

12 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.

Heading Text Quality

2 heading-text-quality issue(s) detected

PASS

2 heading-text-quality issue(s) detected

1 heading(s) are over 120 characters -- likely a misformatted paragraph

Headings beyond 120 characters are almost always full sentences or paragraphs that received heading semantics by mistake (e.g., a CMS editor selected the wrong block type, or a template wrapped a body paragraph in `<h2>`). Screen readers will announce these as "heading" and read the entire paragraph at heading prosody. Affected: - H3: 123 chars

Got: 1 >120-char heading(s)

3 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: 3 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.

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.)

Browser-chrome `theme-color` meta tag present

The page sets `<meta name="theme-color" content="...">`, which Android Chrome uses to tint the status bar and iOS Safari uses for the toolbar background. Brand polish that costs nothing and Just Works.

iOS auto-link for phone numbers disabled (`format-detection: telephone=no`)

The page sets `<meta name="format-detection" content="telephone=no">`, which prevents iOS Safari from auto-converting phone-number-shaped strings into clickable `tel:` links. Common reason: the auto-detection rewrites mid-paragraph DOM and breaks CSS selectors / JS that depended on the specific text. If you want clickable phone numbers, declare them with explicit `<a href="tel:+1234567890">` and keep auto-detection disabled.

Lighthouse Accessibility Audits

Score 91/100 — 3 failing, 25 passed

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.

ARIA

Some ARIA parent roles must contain specific child roles to perform their intended accessibility functions. Learn more about roles and required children elements.

Why this matters

Performance issues directly impact user engagement and conversion rates.
