Accessibility to Site

A page or web site is accessible when it is designed and programmed so that their contents and services are available for any person, independently of the system of navigation. For this, the CNIO Web has followed the directives of accessibility of initiative WAI (Web Accessibility Initiative), along with the fulfilment of the standards defined by the W3C (World Wide Web Consortium).
