What is accessibility?

Web accessibility indicates access capacity to the web and its contents for the highest possible number of persons, regardless of their browsing context or the disability of the users.

By browsing context is meant the devices, browsers, Internet connection speed, peripherals, browser or equipment configuration, ambient conditions, etc.

While disability refers to visual, hearing, motor or cognitive impairments.

The website "http://www.ik4.es/" is firmly committed to making its website accessible and wants its contents to reach the highest possible number of users, regardless of their disabilities. To do this, it uses standard technologies established by W3C and follows the WAI 1.0 Accessibility Guidelines Directrices de Accesibilidad WAI 1.0.

The use of the web standards established by W3C, such as XHTML 1.0 Transitional for valid semantic mark-up and CSS Cascading Style Sheets for design, makes it possible to visualize the web site correctly on different devices and platforms, as well as to print their content .
