Information about accessibility related issues.
Accessibility is a feature that makes navigating the website easier for those with a disability, improving the experience for all users as well as its overall quality. Accessible Web sites allow people to access content with the same equality conditions.
The W3C team in charge of furthering accessibility is the WAI (Web Accessibility Initiative). This work group has drawn up Accessibility Guidelines for Web content, 1.0, WCAG. Its main purpose is to guide the website development towards accessible design, thereby reducing barriers to information.
Given the diversity of people and devices that could access the website, the application is required to adapt to standards that ensure the proper display and access to the information. These standards are defined by different organizations and entities aiming to promote and disseminate good practices to be followed for the greatest interoperability between all participants in the development of web technologies.
In the development of the website, we have followed the specifications and recommendations of the World Wide Web Consortium (W3C), led by Tim Berners-Lee. The validation and verification of different aspects in accessibility issues have been carried out with the use of applications developed by W3C, CTIC Foundation and other applications developed by Fujitsu.
Accessibility on this site
The validation of the project in terms of accessibility, has been carried out by the application TAW3 (WEB 3 Accessibility test) developed by the CTIC Foundation.
This application is a parser that generates useful information and warns about accessibility problems found. It allows for analysis of the site according to the three priority levels and reports the results of the analysis.
Using the TAW3 tool we have resolved all errors or accessibility problems that can be found automatically, as a result of the code generated by the application. However, there are many aspects that need to be reviewed manually as these do not depend solely on the coding of the pages.
To detect possible accessibility issues related to the colors, 2 different tools have been used: Fujitsu Fujitsu ColorDoctor 5.11 and ColorSelector 5.11.
By applying Fujitsu ColorDoctor 2.1 we can emulate different types of colour-blindness (Deuteranopia, Protanopia, Tritanopia) and visualize pages in grayscale.
Fujitsu ColorSelector 5.11 is a program that provides real-time evaluation, it allows one to view if colors in the text of a web site and its backgrounds are easily seen by people with cataracts or color blindness. During the development of a website, Fujitsu ColorSelector determines whether the color combinations in selected text and background are easy to read and also shows the best suiting combination. In this way contributing to the creation of audiovisual content with a high level of accessibility.
Validation of the grammar
We have evaluated the generated HTML coding with a markup grammar validation service, to ensure the pages are well formed and valid.
We have used the validator (X) HTML W3C, this validator is a free code-validation service that checks the conformity of (X) HTML documents in relation to the W3C grammar. The service is available at the URL http://validator.w3.org.
Verification of style sheets
It has also been verified that the definition of style sheets meet the specifications of the W3C. There are problems of interpretation between browsers and situations that can not be corrected, to resolve these error conditions are defined a set of specifications adopted by most browsers and allow the proper display and interpretation of the items shown.
We used a service provided by W3C, which can be found at the URL http://jigsaw.w3.org/css-validator.
