    Chrome DevTools Basics

    The Google Chrome web browser includes a built in set of features for web designers and developers called the Chrome DevTools. Using the DevTools, any webpage can be inspected for bugs and profiled on a number of performance characteristics. Some of the most powerful panels in the DevTools include the Elements panel which allows for interaction with DOM tree and styling, as well as the Console panel, which makes it trivial to access JavaScript functions and test out new front-end code. 22 steps
