Web Content Accessibility Guidelines compliance
The Web Content Accessibility Guidelines (WCAG), produced by the World Wide Web Consortium, are a set of standards designed to make web-based information more accessible to more people. In the words of the Consortium, WCAG 2.0 enables web content to be “ … accessible to a wider range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, photosensitivity and combinations of these.” The Identity Cloud's Hosted Login product is fully compliant with WCAG 2.0 Level AA (the guidelines consist of three levels: A, AA, and AAA).
The following tables list the WCAG 2.0 guidelines, and indicate whether or not Hosted Login meets those specifications. Note that, in these tables, guidelines applicable only to WCAG 2.0 Level AAA are shown in gray. These guidelines are included solely for informational purposes, and are not meant to suggest that Hosted Login is Level AAA compliant.
Principle 1 – Perceivable
Information and user interface components must be presentable to users in ways they can perceive.
| Guideline | Supported | Notes |
|---|---|---|
| 1.1.1 Non-text Content All non-text content that is presented to the user has a text alternative that serves the equivalent purpose, except for the situations listed below: Controls, Input: If non-text content is a control or accepts user input, then it has a name that describes its purpose. Time-Based Media: If non-text content is time-based media, then text alternatives at least provide descriptive identification of the non-text content. Test: If non-text content is a test or exercise that would be invalid if presented intext, then text alternatives at least provide descriptive identification of the non-text content. Sensory: If non-text content is primarily intended to create a specific sensory experience, then text alternatives at least provide descriptive identification of the non-text content. CAPTCHA: If the purpose of non-text content is to confirm that content is being accessed by a person rather than a computer, then text alternatives that identify and describe the purpose of the non-text content are provided, and alternative forms of CAPTCHA using output modes for different types of sensory perception are provided to accommodate different disabilities. Decoration, Formatting, Invisible: If non-text content is pure decoration, is used only for visual formatting, or is not presented to users, then it is implemented in a way that it can be ignored by assistive technology. | n/a | Hosted Login screens do not use non-text elements to convey information. |
