Unfortunately, these are not just imagined scenarios, but real issues that real people have had to deal with in the past, and still have to deal with today, even with the accessibility laws that are currently in place. We believe that the problem is not a lack of caring, but simply a lack of understanding the impact of not taking the time to make all websites and electronic materials accessible to everyone. We hope that this course will help you understand both how and why to make your websites and course materials accessible to all people, regardless of disability, so that no one has to experience these easily avoidable problems.
