description HTML CodeSniffer Overview

HTML CodeSniffer (HCS) is a browser extension and command-line tool that analyzes HTML code for accessibility violations. It's particularly strong at identifying issues related to ARIA attributes and semantic HTML. HCS is highly configurable, allowing users to customize the rules it applies. Its often used in conjunction with other accessibility testing tools to provide a more comprehensive assessment.

While it requires some technical expertise to configure effectively, it offers a deep level of code analysis.
