Website Accessibility
Ideally, websites should be designed with everyone in mind. This includes people with various disabilities. For example, U.S. government sites must comply with the Section 508 Federal Accessibility Standards, which make specific provisions addressing the needs of people with disabilities.
Website accessibility concerns several broad areas that web designers need to consider. These include provisions for creating alternatives or text equivalents for nontext web elements, provisions for creating specific alternatives to script-generated content, and provisions specifically related to choosing colors that can be differentiated.
These are just some website accessibility considerations. For more information, read Web Accessibility: Web Standards and Regulatory Compliance by Jim Thatcher et al. (friends of ED).
