is Web Accessibility?
The explicit purpose of Accessibility is to provide access to information without limitation because of impairment, disability, or handicap so that everyone can surf the net in any condition.
When a website is accessible?
When any person, regardless of their personal limitations, the characteristics of your navigation device or the surrounding environment from which you access the Web, can use and understand its contents.
With this idea comes Accessibility Web Accessibility Initiative, known as WAI (Web Accessibility Initiative). This is an activity developed by the W3C , which aims to facilitate access for people with disabilities, developing accessibility guidelines, improving the tools for evaluating and repairing Web accessibility, carrying out an educational and awareness regarding the importance of accessible design of Web pages, and opening new fields in accessibility through research in this area.

The main idea is to make the Web more accessible to all users regardless circumstances and the devices involved in gaining access to information. With this in mind, an accessible page is to a person with disabilities as for any other person under external circumstances that hinder their access to information (in case of external noise, in situations where visual and auditory attention not available, reduced visibility screens, etc.).
To make Web content accessible, we have developed the so-called Accessibility Guidelines Web Content (WCAG) , whose main function is to guide the design of Web pages to accessible design, reducing as barriers to information.

A tool for automatic analysis of the integral and global accessibility of web sites, items and pages that make up the test web accessibility (TAW). Lets you check the degree of accessibility achieved in the design and development of web pages that allows access to all persons regardless of their characteristics
. It consists of 14 guidelines that provide design solutions and using as an example of common situations in which the design of a page can cause problems of access to information. The Guidelines also contain a series of checkpoints that help detect errors.

Spain has placed a similar initiative under the auspices of Royal Association for the protection and care of persons with disabilities. This Initiative Seminar on Disability and Web Accessibility ( SID @ R )
To help developers and designers a complete review of the accessibility and usability of their Web pages, the Foundation offers Sidar all free, two new tools or applications Web: HERA HERA-XP and .

For its part the English Association for Standardisation and Certification (AENOR ) has developed two standards (139,801 and 139,802) which provide the potential problems identified Disabilities visual, auditory, mental and physical hardware and software in terms of user interface.
in Spain is very advanced accessibility for people with visual impairment or blindness by the ONCE
See: http://www.once.es/
can follow some practical tips for designing pages With a minimum Web accessibility:
- Give an alternative text description to each image or picture of the page.
- Subtitling videos that are incorporated into the Web. There is widespread technology that allows it as Apple's QuickTime.
- Make descriptions of image maps or menus to guide blind people.
There is a page called CARE, which offers much information :
