{n} button(s) without a name in the HTML

Buttons without text and without an aria-label are mute to screen readers — unless the name is set via JavaScript.

button

This is what you should do: Add button text or set an aria-label.

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).

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.

Next steps

  1. {n} of {total} images without an alt attribute. Give each <img> an alt: a short description for meaningful images, alt="" for purely decorative ones.
  2. {n} form fields without a recognisable label. Link each field to a <label for> element or set aria-label / aria-labelledby. A placeholder alone is not enough.
  3. {n} link(s) without a recognisable name in the HTML. Add visible link text, or use aria-label or an image with alt for icon links.
  4. {n} button(s) without a name in the HTML. Add button text or set an aria-label.
  5. {n} CSS rule{nPlural} with possibly too low text contrast. Darken the text colour or lighten the background until the relevant minimum value is reached. Never use colour as the only distinguishing feature.

Method & limits

On 8/31/2026 the HTML that www.heise.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.
