Website Accessibility


As more and more of everyday life and work moves onto the internet, it is becoming increasingly important that what is available on the web is accessible to as many people as possible. But people with physical disabilities such as blindness, color blindness, deafness or limited mobility and those with cognitive or learning disabilities can get left behind. Being aware of issues that affect who is able to effectively use a site can help developers create sites that are accessible to people with a wide range of abilities.

When designing an educational resource, it is worth giving some thought to these issues as well. If you have not had a student in your class with some sort of disability, you probably will at some point. These students should be given the same opportunity to take advantage of any online resources that you create for your classes. Also, it is often the case that creating accessible pages enhances their usability for everyone, including those without disabilities.
