This site has been designed in compliance with the website standards defined by the World Wide Web Consortium (W3C), in particular the Web Content Accessibility Guidelines defined by the Web Accessibility Initiative (WAI). These standards enable the website to be accessed by all, including senior citizens or disabled persons with functional limitations.
A website that complies with accessibility standards benefits all its users. Here a few advantages:
- the website content is logical and organised by order of importance
- page display speed is generally increased by 30 to 80%
- the site does not depend on the web browser used
This website is compatible with all recent browsers that support HTML 4.01 and CSS 2 techniques. It also complies with the XHTML and CSS vocabulary and grammar recommended by the W3C.
Therefore, it will offer optimum performance with more recent browsers all the while continuing to be accessible to older browsers.
