Perceivable

CriticalWCAG 1.4.3 Contrast (Minimum)

{n} CSS rule{nPlural} with possibly too low text contrast

Required: 4.5:1 (normal) or 3:1 (large text). With an “assumed page background” the actual background could not be determined reliably — check in the browser if in doubt. Found among others: {examples}

.ebmex, .deetqq

This is what you should do: Darken the text colour or lighten the background until the relevant minimum value is reached. Never use colour as the only distinguishing feature.

Operable

To checkWCAG 1.3.1 Info and Relationships / 2.4.6 Headings and Labels

No <h1> heading in the delivered HTML

Each page should begin with exactly one h1. On pages built via JavaScript the h1 may only appear in the browser — then check in the rendered DOM.

body

This is what you should do: Insert a meaningful <h1> as the first heading (ideally already server-side).

To checkWCAG 1.3.1 Info and Relationships

Heading level skipped

Sequence: {seq}. Levels should not be skipped (h2 → h4).

h1–h6

This is what you should do: Assign the heading levels without gaps.

Robust

To checkWCAG 4.1.1 Parsing (deprecated, but still relevant for links)

{n} duplicate id attributes

e.g. {examples}. Breaks label-for and aria links.

[id]

This is what you should do: Assign unique ids.

Method & limits

On 8/31/2026 the HTML that t3n.de delivers on a first visit without login was checked, plus up to four linked CSS files from the same domain. Checked: colour contrast (from CSS), text alternatives, form labelling, names of controls, heading structure, page title and page language, zoom lock, duplicate ids, positive tabindex values, landmarks.

Not checked: anything that arises via JavaScript, keyboard operability, visible focus, focus order, screen-reader announcement, content behind login, subpages. The automated test finds roughly 20–35% of WCAG breaches — the rest needs a manual check. A snapshot, not a legal decision.
