Documentation of accessibility observations for Deutsche Telekom – Mobilfunk & OneShop

2.4.6 Headings and Labels (AA) Button label not accurately describing purpose

Priority: Moderate Medium Page: Magenta Tarife Young Observation Permalink
Observation Details

Carousel navigation buttons have labels:

  • Zurück (if disabled)

  • Gehe zurück auf Slide X von 6

  • Gehe vor auf Slide X von 6

Carousel pagination buttons have labels:

  • Zeige Slide X von 6

Observations:

  • Definition of "slide" is vague when showing product cards

  • Carousel shows X slides at a time, moving "by slide" is not ideal

  • Pagination says "X von 6" but on largest viewport only showing 3 pagination buttons

Remediation Notes

Ensure, button labels provide accurate information about button purpose. If button action is "show slide 1 of 3" but label is "show slide 1 of 6", users of assistive technology can get confused.

Possible improvements:

  • Use product names instead of generic slide numbers (e.g. "Show iphone 16e, iphone 16, Samsung Galaxy S25")

  • Use slide ranges instead of navigating "by slide" (e.g. "show slide 1-4 of 6")
