HTML_CodeSniffer is a client-side script developed by Squiz Labs 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".

This tool also powers the Accessibility Auditor within the Edit+ package for Squiz Matrix.

The HTML_CodeSniffer comes with standards that enforce the three conformance levels of the Web Content Accessibility Guidelines (WCAG) 2.0, and the web-related components of the US "Section 508" legislation
