What is accessibility?

Accessibility refers to the fact that something can be used or known without the possible limitations of a user being a barrier.

These limitations may have their origins in physical, technological or structural causes.

Thus, a tool is accessible when users do not need to have, permanently or occasionally, a particular level of intelligence, hearing, vision, mobility or capacity for remembering.

Accessibility on the web

CRITERIA CAIXA, S.A. strives to make its portal accessible, regardless of the kind of hardware, software, web infrastructure, language, culture, geographical location or capabilities of its users.

The aim is to have verified accessibility for all the contents of the portal. To do this, CriteriaCaixa follows the recommendations of the Web Accessibility Initiative (WAI).

The W3C as a guide to web accessibility

The World Wide Web Consortium (W3C) is an international consortium that sets standards for the World Wide Web. It was created in the 1990s to encourage the evolution and inter-operability of the web, emphasising its universality.

In 1997, the W3C created the Web Accessibility Initiative (WAI) to provide guidelines and resources to help make the web accessible.

The W3C developed what are known as the Web Content Accessibility Guidelines (WCAG), whose main function is to guide the design of web pages towards an accessible model.


The web content directives (WCAG 1.0) for level AA web accessibility have already been introduced in our corporate portal.

To meet the requisites set by the WAI, its web standards were used in the construction of the website’s pages, using HTML for content and CSS for their appearance.

For example, the following were introduced:

  • Letters can be enlarged
  • Alternative texts for images
  • Use of style sheets to control layout and presentation
  • Use of headings to explain the logical structure of pages
  • Metadata to add semantic information
