documented & there are constantly new and experimental features
coming out.”
Whether you are a developer or not, Chrome developer tools bring
something for everyone. Today, we’ll review Chrome Developer Tools and
how to maximize them uniquely.
But first, what are Chrome
Developer Tools?
DevTools, called Chrome Developer Tools, is a formidable online
development and debugging tool integrated directly into the Google
Chrome browser. These tools offer a wide range of capabilities and are
intended to ease developers to test and optimize websites, apps, and
other digital content.
The Chrome developer tools are crucial for creating web-based
applications and websites. They support developers in troubleshooting
various problems. However, DevTools is also loaded with handy features
for designers.
The DevTools allow you to instantly review and modify a page's HTML
content, CSS style, and JavaScript functionality. In short, Chrome's
developer tools are different from those of other browsers. But what makes
them different?

Why Chrome Developer Tools are
the best?
The best part of Chrome Dev tools is that it gives developers access to
web browsers and apps' inner workings. With Chrome DevTools, you can
learn about the employed styles, picture sizes, scripts, etc. Hence, despite
feature-packed developer tools in Firefox, Edge, and Safari, Chrome
developer tools are considered the best. Here’s why!

1. It’s In Your Browser
The tools are simple to get. Here are three options
Select Developer Tools from the More Tools menu by clicking the
three horizontal bars in the top right corner of your Chrome browser.

On any page, pick Inspect Element by performing a right-click on an
element.

Windows users can press Ctrl + Shift + I on their keyboard or press
cmd + opt + I on a Mac to get there.
These will launch the DevTools window in your browser's bottom right
corner.
3. An array of features

Several prospects are available in Chrome Developer Tools, making the
development process more efficient. You can assess many areas of your
site and learn important lessons by using the features of chrome inspect
and chrome debugger. Here is a summary of some major features of
Chrome's developer tools:
Elements Panel

With this feature, developers can execute the following:
Real-time analysis and editing of HTML and CSS.
As Software Engineer Yasas Sri Wickramasinghe writes, “CSS Overview
provides a summary of all the styles used in a web page.

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.
Console Panel

Developers can test websites and mobile applications with this JavaScript
Console. To interact with your webpage, you can enter instructions in the
Console. This panel helps developers:
Engage JavaScript and record messages in the browser.
Watch for errors and alerts to identify potential issues.

Execute JavaScript expressions to see the outcomes.
Developers can simply use the console panel to view messages and run
JavaScript.

Memory Panel
According to the Chrome task manager for the profile, this tab shows how
much memory the page uses. Hence, with this tab, developers can:
Monitor memory use and search for memory leaks.

Find inefficiencies, examine heap snapshots, and allocate
timeframes.

tabs, we can identify issues that may be causing the website to load
slowly, and take steps to optimize the code for better performance.”

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

A search bar is at the top because too many features contribute to the
total DevTools functionality. To access it, ensure you are in the DevTools
panel before pressing Ctrl + Shift + P (or Cmd + Shift + P for Mac users) to
open the Tools panel.

DevTools' mode lets you preview your design on various well-liked mobile
devices. Chrome replicates your chosen device's user agent, touch events,
viewport size, and screen resolution.

The Device Mode is effective at simulating a genuine mobile device. With
it, you can
Change the type of mobile gadget.
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.
Network throttling is another excellent sensor to alter while in Device Mode.
The browser network connection is compelled to resemble a standard
cellular data network.

Pro tips and tricks to maximize
Chrome Developer Tools
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.
