Browser Developer Tools

Definition

Browser Developer Tools, commonly referred to as ‘DevTools’, are a set of web authoring and debugging instruments built directly into a web browser like Google Chrome, Firefox, or Safari. They provide deep insights into the inner workings of a webpage, allowing users to assess and tweak the performance, layout, and code of the site. DevTools allow manipulation of HTML Elements, CSS styles, JavaScript debugging, network monitoring and performance checking, among other features.
