Accessible web design – sometimes or accessibility web accessibility – is the art, web pages in such a way that everyone can use it and read.
In the design of websites is often not taken into account that many people have physical limitations. Then make certain techniques of web design “barriers” for their access to the Internet. This can and others missing texts for the description of graphics, an unfortunate choice of color combinations, unclear structured web pages, not use navigation mechanisms be. When eighth but web design to meet the requirements of accessibility, they facilitate people with disabilities to surf the net, instead of preventing them.
When thinking about accessibility, then for example of alternative text for graphics. But what use are such texts, when the access paths or the Navigation is not the site for certain access methods may be used? Barrier-free web design includes not only certain technical details of programming, but must be understood as a concept which can make the entire information system accessible.
A frequent barrier to Web sites is the lack of device independence. For example, is often assumed that each visitor is using a mouse. Experienced computer users know this: the advantages of the keyboard are located opposite the mouse operation in the speed, but people who have a mouse is not available or can not operate, are on a website that the keyboard is not operated, not very get very far. The same applies to the reading of information: an alternative to monitor the printers are not only available but also sound, small screen or Braille display.
If designers and programmers have understood that not every visitor to an “average surfer” is that accessibility also means increased flexibility and that the demographic factor is a key economic aspect of the design of websites, then the process can begin the transformation. With the aim to increase the usability of an information system, you create user-friendly interfaces, under the various circumstances in which the user is located, and with the different skills that he brings, can be operated. The technical aspects of accessibility are also a prerequisite.
Due to the usual visual access to the Web, it is difficult to imagine for many Web designers, such as a blind man can read a web page at all. Dealing with computer tools such as a screen-reader is definitely getting used to, since the operation of the resource follows a very different approach than, say, operating the computer mouse. The understanding in dealing with this software will help in the implementation of an accessible website. You will therefore find in these pages some links to software tools of validators to demo versions of various computer tools.
