You can do a lot using browser DevTools, such as debugging, editing HTML elements, editing CSS properties, checking device, and tracking Javascript errors. Every developer should be aware of using different tabs (elements, console, network) in DevTools to make their work easier and faster. It depends on your browser whether you can use DevTools such as Chrome DevTools, Firefox DevTools or whatever browser you are using. People generally prefer using Chrome DevTools to develop, test and debug a web application. Still, it's the developer's choice which browser they are using to develop the website.
