Focusing product card by keyboard navigation does not add visible focus state.

Remediation Notes

A focus state must be defined for all interactive, focusable elements. Ideally, a visual distinct focus state uses an outline or other larger area changes to the product card.

If using color change for focus state, ensure to meet minimum color contrast between different states (1.4.3 Contrast (Minimum)) and to not only rely on color change (1.4.1 Use of Color).

The section "Neue Ideen für eine neue Welt" has news tiles with images. The images are wrapped in <a> elements. The focus outline on keyboard focus is partially obscured, due to an overflow: hidden on the parent container class="Container__container___XYZ styles_netzbrick__XYZ".

Remediation Notes

Evaluate removing overflow: hidden.

Observation Details

The "Empfehlung ansehen" link is focusable by keyboard navigation. The pop-up window showing the link however just becomes visible after a selection of sports channels. As is, the focus is not visible.

Remediation Notes

Focus of all interactive elements must be visible. The "Empfehlung ansehen" pop-up and link must not be focusable while no "Empfehlung" is set. When focused, the pop-up must be visible for the focused link to be visible as well.

Side note: The pop-up also disappears on scroll, even when the link inside is focused. This is another issue that should be fixed at the same time. See e.g. "UK.GOV Design System – Notification Banner" as an idea.

Observation Details

The buttons in section "Das komplette Sport Programm" with sports channel logos are duplicated. The HTML structure is as follows:

<div class="styles_Program__switch__10Eau">
  <button type="button"><img alt="Wow Logo" src="..." /></button>
  <button type="button"><img alt="Dazn Logo" src="..." /></button>
  <button type="button"><img alt="MagentaSport" src="..." /></button>
  <div class="styles_Program__switch-window__dWIIF">
    <div>
      <button type="button"><img alt="Wow Logo" src="..." /></button>
      <button type="button"><img alt="Dazn Logo" src="..." /></button>
      <button type="button"><img alt="MagentaSport" src="..." /></button>
    </div>
  </div>
</div>

This leads to three buttons not being visibly focused before reaching the actual buttons. See screenshot for jump from element 8 to element 12 in focus order. Elements 9-11 are the "hidden" buttons.

Remediation Notes

Ensure, cleaning up code, by removing duplicate and unused parts to provide clean, semantic HTML code.

Side note: Consider, moving the section to a tab group structure to match visual presentation, functionality, and code markup.

Observation Details

The play buttons in video pop-up thumbnails are used as interactive elements to start the video playback. The button does not have a visible focus indicator, despite being focusable.

Remediation Notes

Ensure visible focus indicators on all interactive, focusable elements. For a base structure of a play button, refer to audit sample page "Kids Watch".

Remediation Notes

Ensure visible focus state on all focusable elements. To remediate, consider using semantic HTML elements details & summary as opposed to non-interactive description list element.

Observation Details

Focusable elements must have a visually distinct focus state. Moving keyboard focus to a focusable element must clearly identify the element as being focused. If this is not the case, sighted users of keyboard navigation will have difficulties navigating a page. Especially when multiple focusable elements do not show visible focus indicators, properly navigating the page may become impossible.

Focussing a product tile by keyboard navigation does not visually indicate the tile being focused. This makes it incredibly difficult to navigate the page with a keyboard.

Remediation Notes

Ensure product tiles (and all other focusable elements) have visual focus states that differ enough from the default states. Keep in mind to adhere to success criterion 1.4.1 and ensure, when only using color to indicate a focus state, that the color difference must be 3:1 or higher.

Ensure, all focusable elements have a visible focus indicator.

  • The focus indicator should ideally be clearly visible

  • The focus indicator should not solely rely on change of color (see 1.4.1 Use of Color)

  • The focus indicator should not create contrast issues of focused text content (see 1.4.3 Contrast (Minimum))

  • The browser's native focus indicator can be used if it itself passes contrast minimum requirements to the element's background (see 1.4.11 Non-text Contrast).
