“Web accessibility” refers to content designed so that disabled users can access it. Accessibility involves a wide range of disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological.
Accessibility overlaps with other disciplines, such as responsive web design, usability, and search engine optimization. As a result, accessible websites can have an increased audience reach, better search results, and demonstrate social responsibility to users.
Here is a list of tools and plugins for website accessibility, including plugins and ecommerce themes for WordPress. Most of the basics of accessibility are easy to implement after reviewing common issues and solutions. Whenever possible, incorporate accessibility at the beginning of any project.
