We aim to provide you with a website that is accessible to all, including those with a disability, in particular those with a visual impairment. For this, we use the Web Content Accessibility Guidelines version 2.0  (WCAG-2.0) compiled by the Web Accessibility Initiative (WAI) from the World-Wide-Web Consortium (W3C), the organisation that looks after the standardisation of the internet.


The guidelines can be implemented to three, increasingly more compliant levels: A, AA, and AAA. Our intention on this website is to provide you with AA conformance to the guidelines. This means that accessibility is a concrete requirement during the development of this website and is taken into account at every technical level of the system, as well as during the authoring of the content.

  • All pages on this website should conform to AA-level (see exceptions),
  • The technology used on this website includes HTML 5, CSS 3 and JavaScript,
  • NVDA has been used for testing screenreader effectiveness.


We include certain user-interface elements on our website which, due to their technical nature, are difficult or even impossible to conform to the guidelines. On this website, elements explicitly excluded from conformance are:

  • The "slider" across the top of the pages.
