Content Management Systems (CMS), like Drupal 8, allow authors to edit web content using WYSISWYG editors. Most CMS authors have little understanding of accessibility principles and the technical details of HTML accessibility to insure the content they create is accessible to people with disabilities. Some CMS editors are configured with an accessibility checker, but the utility of this feature is dependent on the author invoking the checker. A checker-only approach reinforces the remediation stereotype for accessibility, which is extra work for the author. The A11yFirst project goal is to provide a proactive approach to making web content accessible by providing features that guide authors in creating accessible content by default (e.g. headings), just in time accessibility feedback (e.g. link text and text alternatives for images), and help information on making accessible content. Information will be provided on the A11yFirst for CKEditor distribution and the Drupal 8 A11yFirst Editor Enhancements module.
