WordPress is a popular content management system (CMS) that enables users to create a website or blog from scratch, or to improve an existing website. WordPress is used by millions of people around the world, including many who have disabilities.
The WordPress accessibility team is committed to making WordPress accessible to as many people as possible. This includes people with disabilities, those using assistive technologies such as screen readers, and those with slow internet connections.
There are many ways to make a WordPress theme accessible. In this article, we will cover some of the most important accessibility features to consider when developing a WordPress theme.
