These will launch the DevTools window in your browser's bottom right corner.

  • Use the selector tool to identify particular web page components.
  • They can access the box model and computed styles for the chosen items.
  • This feature helps developers to choose a particular element of a web page and inspect its underlying structure, including code, attributes, connected components like style, and more.

  • Engage JavaScript and record messages in the browser.
  • Watch for errors and alerts to identify potential issues.
  • Execute JavaScript expressions to see the outcomes.

This panel is designed to maximize the speed at which your website loads, as its name implies. With it, you can -

  • Measure detailed performance to identify and fix rendering and loading problems.
  • Use the Chrome Developer Tools timeline to see different events and interactions.

  • Show or hide the device frame, or even take screenshots and debug the device.
  • Simulate viewport-restricting toolbars like the on-screen keyboard that appears when a user chooses a form entry.
  • Change the geolocation of the "device" to make it appear like the mobile gadget was truly mobile-friendly. You must include this capability when developing any geolocation-enabled functionality for your website.

So, you have learned why Chrome developer tools are so popular, but how can you use them? Here are a few tips to help you get the most out of Chrome DevTools, whether you're new to using them or an experienced pro.

1. Exploring the Command Menu

The shortcut for executing commands or code and getting to any visible line of code in your application is the command menu on Chrome DevTools. It's an excellent method for navigating menus and carrying out debugging tasks.

Simply click on the three vertical dots in the Chrome DevTools' upper right corner to enter the command menu, where you will find the "Run Command" option. Ctrl + Shift + P on Windows or ⌘ + ⇧ + P on Mac will also work to launch the command menu.

All you need to do here is enter "?" to see a dropdown of all available actions after opening the command menu. You only need to press a few keys to turn off JavaScript or jump to a certain line in your code.

So be sure to use the command menu the next time you use DevTools. It will greatly speed up your process and save you time.

2. Copying Attributes & Selectors

The ability to copy and paste items is one of the most beneficial features of Chrome DevTools. For instance, if you like an element on a web page, you can right-click it and choose "Copy CSS" to copy the element's whole stylistic data. You may copy and paste it into your code to view how it appears.

It's a fantastic approach to rapidly add styles to your web application without manually creating all CSS by hand. This functionality may be extremely helpful when dealing with complicated codebases or adhering to a particular design.

For instance, you can right-click an element on a web page of your choice & choose “Copy CSS” to copy all the stylistic data for that desired element. It can then be pasted to monitor its performance.

3. Creating Code Snippets

Do you want to experiment with code like on CodePen? Snippets in Chrome DevTools can serve as your quick and easy coding playground. Here, code can be written, edited simultaneously over several lines, and saved. 

The best thing is that your snippets don't need to be a part of your main web application; you may use them on any web page. For instance, the screenshot below shows the site for the DevTools documentation on the left and some source code in the Sources > Snippets window on the right.

Here is the source code snippet that logs a message and inserts an <p> element with the message instead of the HTML body on the homepage:

The "Hello, Snippets!" message that the snippet logs are then displayed in the Console drawer, and the content of the page changes when you click the Run button.

4. Force Element State

It might be useful to observe how an element appears in various states when you're working on decorating it in HTML. For instance, you can view an element's appearance when it is focused or hovered over.

You don't need to move your pointer continuously whenever you want to test altering the style or debug the hover states of buttons. You can force any state using Chrome DevTools and utilize your mouse more effectively by copying or altering styles. 

The Elements tab's styles tab allows you to force an element's state. For instance, it may be in a hover, focus, active, or visited state. The component whose state you wish to force has to be clicked on once.

5. Searching Code

Imagine you are now working on your project and are trying to find a certain piece of code. Your goal can be to optimize a function or modify a string. Whatever it is, DevTools provides a useful function that enables you to search for anything in all loaded scripts.

Click the three dots dropdown to reveal the Search bar at the bottom of DevTools, then enter your search term. You may also use Ctrl + Shift + F on Windows & ⌘ + ⌥ + F for Mac. DevTools will provide results for every instance where your query is applicable, regardless of whether it uses case sensitivity or a regular expression.
