In line with these goals, we follow the general principles of web usability and universal design and, where feasible, endeavor to make the Oxford Handbooks Online site (OHO) accessible to all regardless of physical or cognitive impairment or the device used. We are currently targeting adherence to level AA of the World Wide Web Consortium (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1), in order to help our users take full advantage of the accessibility features provided by their chosen device, web browser or operating system.
