CSS Class Highlighter is a Chrome extension designed for developers, designers, and QA professionals to streamline their workflow by inspecting and highlighting CSS classes on web pages. By enabling Inspect Mode, users can hover over any element to instantly view its tag, ID, classes, and key computed styles, complete with color swatches. The extension also features a Class List panel that allows users to search and view an inventory of all classes present on the page, along with usage counts, enabling quick identification and debugging of styles.

This tool enhances efficiency by allowing users to customize highlights, including outline or overlay styles, colors, thickness, and duration. It promotes faster debugging, effective design audits, and improved QA processes by enabling users to highlight all elements with specific classes. With minimal permissions required and a user-friendly interface, CSS Class Highlighter is a valuable asset for frontend engineers, UX designers, and anyone needing to inspect CSS effectively.
