Chrome DevTools

Chrome DevTools is a set of web developer tools built directly into the Google Chrome browser. DevTools can help you edit pages on-the-fly and diagnose problems quickly, which ultimately helps you build better websites, faster.

With DevTools you can view and change any page. Even the Google homepage, as the video demonstrates.
