Non-accessible content

Some pages of the website contain non-accessible content:

  • Some pages contain link headings that only describe the function of the link for an anchor element.
  • Some pages contain text elements with underlining or special characters without semantic highlighting.
  • Some pages contain section headers that are not identified by h1-h6 tags.
  • Some pages contain elements with insufficient contrast, i.e. with a contrast ratio of less than 4.5:1 between text (including text in image form) and text background.
  • Some pages contain frame and iframe elements that are not labelled accordingly via a title attribute.
  • Some pages contain duplicate ID values.
  • Some pages do not use form elements and links.

Available alternatives

There is currently no alternative for the non-accessible content listed above. However, we are very keen on removing these issues. We therefore assume that the aforementioned problems will be resolved by September 2024.
