The Chrome DevTools provide web developers with tools to debug websites and applications built into the Chrome browser. Some key panels include the Elements panel for inspecting and modifying the DOM and CSS, the Network panel for optimizing page load performance and debugging requests, and the Console panel for logging information and interacting with JavaScript. The Audits panel identifies common issues that affect performance, accessibility, and user experience. This document focuses on introducing the Elements, Network, Console, and Audits panels of the Chrome DevTools.
