This report reflects the findings of a high-level assessment of O'Reilly eBooks Platform for its conformance with the W3C Web Content Accessibility Guidelines version 2.1 (WCAG 2.1). The analysis uncovered only a few issues with WCAG 2.1 compliance and most of the problems that were detected with the use of automatic analysis. These are the main issues to focus on correcting to improve access for all potential users of the system.
1. Use of Color & Navigation - The biggest issue with the current system is keyboard focus. Keyboard focus is primarily conveyed with changes in color, which is a violation of these two success criteria (SC 1.4.1/2.4.7). This will become more of a problem with WCAG 2.2, which has updates specifically regarding the use of a focus ring. This can be easily addressed using the standard browser focus ring.
2. Compatibility: There are a few minor issues with Name, Role, Value (SC 4.1.2) and many of the pages do not contain an h1 heading.
