In the United States, twenty percent of adults have a disability, according to the Centers for Disease Control and Prevention. Disabilities that may impede a person’s ability to use a website include:
Deafness and loss of auditory capacity
Limited visual acuity and blindness
Cognitive medical conditions
Other types of disabilities which impede content consumption.
The World Wide Web consortium (W3C) defines accessibility as the practice of insuring that people with disabilities can perceive, understand, navigate, and interact with websites and tools, and that they can contribute equally without barriers.
In spite of the emphasis given to accessibility issues in every web standard, actual implementation of accessibility best practices is still sub-par in many websites and web applications. In this blog post, I’ll discuss some of these best practices, explore the current state of accessibility tools, and give you a few pointers on things that you can do today to improve the accessibility of your website or applications.
