How to use the CSS Overview tab to audit a web page design?

The CSS Overview tab in modern browser developer tools is a powerful tool for conducting a comprehensive style audit on a web page. It helps designers and front-end developers quickly find discrepancies in the color scheme, fonts used, and spacing, ensuring a unified visual style for the project.

To use this tool, open the developer console, go to the top tab bar, and find the CSS Overview item. If it is not there, click the three-dots icon to expand the list and select the desired item. Then click the Capture overview button to start the scanning process for the current page.

After the analysis is complete, the tool will generate a detailed report divided into several semantic categories. In the colors section, you will see the entire site palette, including background colors, text colors, and their usage frequency, which allows you to identify random shades that accidentally got into the project. The fonts section displays all font families, their sizes, weights, and line heights, helping you control typography.

Using CSS Overview is especially useful when redesigning sites or checking a project for compliance with a design system. This approach saves hours of manual style checking and allows you to quickly eliminate visual defects before handing the project over to production.
