Compatibility with standards

This website has been defined and programmed following the guidelines of the WAI (Web Accessibility Initiative,, that sets international standards in terms of the creation of online content accessible worldwide.

Accessibility guidelines

Various measures have been taken to make the website more accessible, including:

  • Logical order of presentation of elements on screen.
  • Simplified browsing system, dropdown menus are not used.
  • Descriptive text of images.
  • Keyboard access to the main options.


Most browsers support direct access to specific links by using certain combinations of keys (access keys) defined on the website.

For example, in Windows by pressing  Alt + access key(in Internet Explorer you must also press  Enter); for Mac users, it works by pressing Ctrl + access key.

The following access keys are available on our web portal:

  • 0 Accessibility.
  • 1 Home page.
  • 2 Skip navigation.
  • 3 Website map.
  • 4 Search.
  • 8 Legal information.
  • 9 Contact.


Most links whose text does not fully describe the destination have "title" attributes with an explanation.

Wherever possible, links are written in such a way to make sure they make sense out of context. Some browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can extract the list of links on the current page and allow the user to browse this list. Bearing this in mind, links are not duplicated and if they are, this is because they access the same content.

There are no javascript pseudo-links. All links can be followed on any browser, including when javascript is disabled.
