This site is built using the Wiking web application development framework. One of the major aims of this system is providing equal access to all users, including people with handicaps and/or special needs. Wiking also tries to be neutral to user's software, hardware and settings. Thus the resulting pages should be usable with any browser, font type or size, screen resolution, assistive technologies etc.
The system was developed considering formal accessibility standards, such as Web Content Accessibility Guidelines 2.0 or Section 508 as well as real end user experience. Accessibility and usability was tested with different combinations of assistive technologies, especially screeen readers.
You will find information about navigation and accessibility related features in the chapter Navigation of the User's Manual.
