We want our website to be accessible to everyone. That's why we strive for accessibility.

  • The website is optimized for different resolutions and provides a separate optimized display for mobile devices.

The website was tested against various criteria. The test was based, among other things, on the requirements of the Web Content Accessibility Guidelines (WCAG 2.1) at conformance levels A and AA, as specified in the EU standard. The barriers identified during the test have largely been resolved.
