Infobase Credo Reference: Using Credo Reference: Accessibility and Support for All Learners

The Web Content Accessibility Guidelines (WCAG) define requirements for designers and developers to improve accessibility for people with disabilities. It defines three levels of conformance: Level A, Level AA, and Level AAA. The Infobase Administration Portal is partially conformant with WCAG 2.1 level AA. Partially conformant means that some parts of the content do not fully conform to the accessibility standard.

HTML_CodeSniffer is a client-side script that checks HTML source code and detects violations of a defined coding standard. HTML_CodeSniffer is written entirely in JavaScript, does not require any server-side processing and can be extended by developers to enforce custom coding standards by creating your own "sniffs".
