O’Reilly is committed to making its online services and content accessible to the widest possible range of users and is continually working to improve its services to support accessibility for everyone.
We seek to conform to W3C’s Web Content Accessibility Guidelines (WCAG) 2.1 to create a better learning experience for everyone in our audience. WCAG 2.1 aims to make web content more accessible by providing a shared set of technical guidelines, success criteria, and target conformance levels.
Each of the guidelines falls under one of four guiding principles, which state that content on the web should be:
- Perceivable: Information and user interface components must be presentable to users in ways they can perceive.
- Operable: User interface components and navigation must be operable.
- Understandable: Information and the operation of the user interface must be understandable.
- Robust: Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.
The conformance levels are A (essential for accessibility), AA (ideal), and AAA (specialized). Whenever possible, we aim for AA conformance.
The O’Reilly learning platform has been created with accessibility in mind. The building blocks of our applications leverage both inclusive design principles and WCAG 2.1 AA standards to benefit the broadest range of users. Each component uses semantic HTML markup under the hood and proper color contrast, and each is navigable by both the mouse and keyboard and reachable by screen readers.
In addition to providing content in a variety of modalities, we give our members tools to customize their own learning experience, such as the ability to control font size, color scheme, and other typographical preferences along with support for video closed captioning, transcripts, and adjustable playback speeds.
Voluntary Product Accessibility Template (VPAT)
Working with Accessibility Partners, O’Reilly maintains and updates annually an assessment of the O’Reilly learning platform—including the web, iOS, and Android applications—using WCAG 2.1 AA standards as well as Section 508 standards. This assessment forms the basis of O’Reilly’s Voluntary Product Accessibility Templates (VPATs).
O’Reilly’s VPAT 2.4 shows the level of conformity to these standards within the O’Reilly learning platform and its mobile applications (for both iOS and Android versions) and outlines how our service features aim for accessibility and how they may satisfy our customers’ own needs. To request a copy of our most recent VPATs, please contact
We hope you find our voluntary self-assessment helpful. Please contact us if you have any questions or comments to share related to accessibility. We’re committed to improving our applications to support accessibility for everyone and consider recommendations for improvement when planning and implementing further development of the O’Reilly learning platform.
