Landmark Structure

Action

3 landmarks

FIX

3 landmarks

No <main> landmark found

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

2 <nav> landmark(s) found

1 of 2 <nav> elements are unlabeled

Multiple navigations need aria-label to distinguish them for screen readers.

No contentinfo (footer) landmark

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

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

Why this matters

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>.

Multiple navigations need aria-label to distinguish them for screen readers.

Why this matters

Some <nav> elements lack aria-label — screen-reader users hear 'navigation' multiple times with no way to distinguish them.

Learn more ▾

When a page has multiple <nav> regions (primary, footer, breadcrumb), each needs aria-label or aria-labelledby. AT users navigate by landmark; identical 'navigation' announcements force them to enter each one to discover purpose.

Source: WAI-ARIA Authoring Practices

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.

Favicon & Branding

Action

1 icon(s) detected

FIX

1 icon(s) detected

No favicon.ico at site root

Some older browsers, bookmark tools, and RSS readers look for /favicon.ico. Add one as a fallback.

HTML icon links detected

No apple-touch-icon detected

iOS devices use this when users add your site to their home screen. Add <link rel='apple-touch-icon' sizes='180x180' href='/apple-touch-icon.png'>.

Web Manifest

Action

FIX

Not found

No web manifest found

No manifest at standard paths (/manifest.json, /site.webmanifest). A manifest is optional but enables PWA features like home screen installation and standalone display.

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: #000014

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

External CSS files may contain prefers-color-scheme rules not visible to this scan.

When users print this page, they get the screen layout including navigation and non-essential elements. Add @media print rules to hide navigation and optimize layout for paper.

Heading Hierarchy

33 headings, 2 skip(s)

REVIEW

33 headings, 2 skip(s)

Single H1 present

Heading level skipped: H2 → H5 (missing H3)

Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.

Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.

Why this matters

Skipping heading levels breaks the document outline — screen-reader users lose track of section nesting.

Learn more ▾

Screen reader users navigate by jumping between headings (H1 → H2 → H3). Skipping (H1 → H3) breaks the sense of hierarchy. Use sequential levels even if you don't like the default styling — restyle with CSS instead. WCAG 1.3.1 (Info and Relationships) treats this as an A failure.

Mobile Keyboard & Autofill

Action

4/8 eligible field(s) missing autocomplete or inputmode

REVIEW

4/8 eligible field(s) missing autocomplete or inputmode

4 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: tel, email.

Got: <input type="tel" name="telefon" id="f-phone">, <input type="email" name="email" id="f-email">, <input type="tel" name="telefon" id="m-phone">, <input type="email" name="email" id="m-email">

Mobile-Readable Font Sizes

97% of visible text renders at >= 12 CSS px (4 below threshold)

REVIEW

97% of visible text renders at >= 12 CSS px (4 below threshold)

4 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> 11.0px ("DC Montage"); <a> 11.0px ("Impressum"); <a> 11.0px ("Datenschutzerklärung"); <a> 11.0px ("Cookie-Richtlinie").

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.)
