- Authoring tools are software used to create and publish web content, like content management systems, blogging tools, and word processors. - The Web Content Accessibility Guidelines (WCAG) and Authoring Tool Accessibility Guidelines (ATAG) provide standards for making authoring tools and their output accessible, but awareness of ATAG is low. - For authoring tools and content to be accessible, tools must make it easy for all users, including non-experts and people with disabilities, to create accessible web content. Evaluation and selection of authoring tools should consider how well they support the creation of accessible content.
