Overview

Product summary

Review the store description, core capabilities, and common use cases.

This extension, is designed to simplify CSS debugging and layout inspection. It instantly adds colorful outlines to HTML elements, making it easy to visualize and identify different elements on a webpage.

The extension solves the common problem of struggling to understand the structure and layout of a website. Instead of manually inspecting elements in the browser's developer tools, this extension provides a quick visual overview of the page's underlying structure.

When the extension's icon is clicked, it injects a script into the current tab that toggles the CSS outlines. The script uses predefined color mappings for different HTML elements, and it dynamically generates and injects CSS rules to apply the outlines.

It functions similarly to the old Pesticide extension but is compatible with Manifest V3. The source code contains no third-party dependencies.
