Web Accessibility is based around maintaining certain techniques in the design of a web page to allow people with disabilities easy access to the information contained on the page. Some of the things that effect accessibility include markup, use of javascript, image and media usage as well as basic layout techniques.

Consider your audience... they may not be able to see, hear or move, they may have a text only browser or an older browser. Accessibility standards are designed to make web sites usable for these people and it's becoming increasingly important that Web designers and developers take note of their requirements. In fact in certain countries it's a legal requirement whilst in others there are legal precedence for the requirement of accessible web sites.
