An important consideration when designing a website is how people will work with it. We want to design our websites in a way that they are useable by everyone in our anticipated audience - bet that everyone in the world, university students, employees at our company, or customers of our business. But there is a segment of each of these audiences that is often overlooked - those with disabilities.

The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect.
- Sir Tim Berners-Lee

Globally, about 15% of the world’s population experiences some form of disability. The UN Convention on the Rights of Persons with DIsabilities recognizes access to the Web, and the information it makes available, as a basic human right. Many countries have followed suit, even codifying accessibility requirements into laws like the Americans with Disabilities Act.

In short, it is vital when you author a website, you consider how those with disabilities will interact with it. Moreover, building your website to be accessible will also make your website more usable for all users.
