To check web elements, you can open the developer tools by right-clicking and selecting "Check" or using the shortcut key F12/Ctrl Shift I/Cmd Option I. 1. Right-click the target element to view its HTML structure and style, which is convenient for troubleshooting layout and style issues; 2. Use shortcut keys or click the Select Element button to locate any position of the page, which is suitable for frequent switching areas; 3. You can view and temporarily modify the style rules in the Elements panel, double-click the attribute value to adjust, and restore it to its original state after refreshing; 4. Use the Ctrl F/Cmd F search function to enter class names, label names or attributes to quickly locate specific elements or styles in complex pages to improve debugging efficiency.
Checking web page elements is an important means to debug front-end problems, learn web page structure, or modify page content. The Chrome browser's own developer tools (DevTools) are powerful and very convenient to use. Here are some simple and practical methods of operation.
Right-click the element to open the inspection tool
The most direct way is to right-click the web page element you want to view, such as a paragraph of text, a button or an image, and then select "Inspect" in the pop-up menu. At this time, Chrome will automatically open the developer tool and highlight the HTML code for the corresponding element. This method is especially suitable for you to quickly view the structure of a specific part, or to troubleshoot style issues.
For example, if you find that a button is not displayed properly, click "Check" to see directly what CSS class names, inline styles it uses, and even whether the layout is affected by the parent element.
Open the developer tool with shortcut keys
If you are used to keyboard operations, you can press F12 or Ctrl Shift I (Windows/Linux), or Cmd Option I (Mac) to open DevTools. After opening, you can click the "Select Element" icon in the upper left corner with your mouse (it looks like an arrow), and then click anywhere on the page to select the corresponding element. This method is suitable for situations where frequent switching of different regions is required.
- Press F12 to open the tool
- Click the Select Element button (or press Ctrl Shift C)
- The mouse becomes a cross cursor, click anywhere on the page to select elements
View and modify styles
In the Elements panel, the style information of the currently selected element is displayed on the right. Here you can see all the CSS rules applied to this element, including inherited styles. If you want to temporarily test the style change effect, you can directly double-click the attribute value to modify it, such as changing the font color to red or adjusting the margin size. Note that this is just a temporary change, and refreshing the page will return to its original state.
Sometimes you will find that a style is crossed out, which means it is overwritten by the rules behind it. At this time, you can flip up to see who covered it, or check/uncheck some check boxes for quick debugging.
Use the search function to find specific elements or styles
If the page structure is relatively complicated, it may not be realistic to find an element manually. You can press Ctrl F ( Cmd F on Mac) in the Elements panel to open the search box, enter the class name, label name or attribute, and you can quickly locate the relevant code. For example, if you want to find a link with a class that is .nav-link , search for this class name directly to list all matching elements. It can also be used to find specific style rules to help locate problems faster.
Basically these commonly used methods. Although it seems that there are not many steps, it can greatly improve debugging efficiency after proficiency.
