Freedom to Connect
The right to Internet access, also known as the right to broadband or freedom to connect, is the view that all people must be able to access the Internet in order to exercise and enjoy their rights to freedom of expression and opinion and other fundamental human rights, that states have a responsibility to ensure that Internet access is broadly available, and that states may not unreasonably restrict an individual’s access to the Internet (via Wikipedia).
This includes all people, including those with various disabilities.
What is WCAG 2.1
Web Content Accessibility Guidelines (WCAG) 2.1 covers a wide range of recommendations for making Web content more accessible.
Following these guidelines will make content more accessible to a wider range of people with disabilities, including accommodations for blindness and low vision, deafness and hearing loss, limited movement, speech disabilities, photosensitivity, and combinations of these, and some accommodation for learning disabilities and cognitive limitations; but will not address every user need for people with these disabilities. These guidelines address accessibility of web content on desktops, laptops, tablets, and mobile devices.
Following these guidelines will also often make Web content more usable to users in general.
