Web accessibility is concerned with ensuring people with disabilities can participate online in an equitable way. Creating content is key to participating, and for true inclusion, people with disabilities must be able to contribute as well as consume content. Often the tools we provide and design patterns we adopt to support content authoring have significant accessibility limitations that make them difficult or impossible for people with disabilities to use. In this talk, we’ll focus on some common design patterns that support user content creation, including online forms, discussion forums, and WYSIWYG text editors, and walk through how we can optimise their accessibility.
