To inspect an element, simply click on the icon and mouse over to target the desired element on your web page, then, it will be highlighted in blue. From there, you can :
- Preview and modify the CSS styling of the selected element

The Styles tab displays all of the styles that have been defined for the selected element, including those that are inherited from parent elements or defined in both inline CSS styles or external stylesheets. Additionally, the Styles tab displays all styles that have been applied to an element, including those that have been overridden by other styles.
This is extremely useful when you are trying to inpect and diagnose issues related to the styling of a webpage, such as font size or color, border properties, or layout issues.
In this example, you can change the font color of a title on a web page by selecting the title element and modifying its color property in the Styles panel on the right side of the Elements tab. As you modify the property, you will see the changes reflected on the page immediately.
The Computed tab is another powerful feature within the Google Development Console tool. Unlike the Styles tab, which displays all of the defined styles for an element, the Computed tab will only shows the actual computed values of each CSS property that are rendered on screen.
This is very useful when you want to have a quick overview of the rendered CSS or trying to identify and troubleshoot issues related to the specificity and inheritance of CSS styles, as it shows how different styles are being applied and combined to create the final appearance of an element.
3. Event Listener
The Event Listener tab is a powerful tool for us to debug event-related issues on a web page. When you select an element on a web page, the Event Listener tab allows you to see all the event listeners that are attached to that element.
For example, let’s say that you are working on a form and you notice that the submit button is not submitting the form data when clicked. You can use the Event Listener tab to inspect the button element and check if there is an event listener attached to the button’s click event. If there is no event listener or if the event listener is not properly defined, you can modify the code to add or fix the event listener, and then test the button again.
