What is the main purpose of using browser developer tools?

The main purpose of using browser developer tools is to inspect and debug web pages. These built-in tools, available in modern web browsers, allow developers and designers to examine the HTML structure, CSS styles, and JavaScript behavior of web pages in real time. By using these tools, you can manipulate elements on the page and instantly see changes, making it easier to identify and fix issues with layout, functionality, or performance.

Additionally, browser developer tools provide features such as the console for running JavaScript, network monitoring to view resource loading times, and performance auditing to optimize website speed. These functionalities are essential for ensuring a smooth user experience and effective website operation.

The other options, such as creating complex animations, improving graphic design, or managing user databases, do not directly align with the primary functions of developer tools. While these tasks may be part of web development, they typically require different software or processes not reliant on browser developer tools specifically.
