Accessibility guidelines

Different measures have been taken to make the website more accessible, including: on-screen items presented in a logical order. Simplified browsing system and drop-down menus not used. Descriptive text of the images. Access to the main options using the keyboard.


The majority of links whose text does not fully describe their destination have title attributes providing clarification. Whenever possible, the links are written in such a way that they can be understood out of context. Some browsers (such as JAWS, Home Page Reader, Lynx and Opera) can extract the list of links from the current page and allow the user to browse from the list. Taking this into account, links are not duplicated and where they are, it is because they access the same content. There are no Javascript pseudo-links. All the links can be followed in any browser, even if Javascript is disabled.
