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 accessibilityfor everyone.
We seek to conform to W3C’sWeb Content Accessibility Guidelines (WCAG) 2.1to 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 targetconformance levels.
Each of the guidelines falls under one of four guiding principles, which state that content on the webshould be:
- Perceivable:Information and user interface components must be presentable to users in ways theycan perceive.
- Operable:User interface components and navigation mustbe operable.
- Understandable:Information and the operation of the user interface mustbe 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 forAA 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 byscreen 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 adjustableplayback speeds.
Voluntary Product AccessibilityTemplate (VPAT)
Working withAccessibility 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 AccessibilityTemplates (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. Pleasecontact us如果你有任何问题或评论分享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’Reillylearning platform.
