CSS Inspector
CSS Inspector is a browser developer tool feature that allows developers to inspect, edit, and debug CSS styles on web pages in real-time. It provides a visual interface to view the CSS rules applied to HTML elements, including computed styles, inheritance, and box model properties. This tool is essential for front-end development to troubleshoot layout issues, test style changes, and understand how CSS affects page rendering.
Developers should use CSS Inspector when debugging visual issues, optimizing page performance, or learning how CSS works on existing websites. It's particularly useful for responsive design testing, identifying style conflicts, and experimenting with CSS changes without modifying source code. This tool is integrated into all major browsers like Chrome DevTools and Firefox Developer Tools, making it a standard part of the web development workflow.
