Features & Capabilities

The Toggle CSS Outline Chrome extension provides a handy browser button that lets you switch a red outline around every element on a webpage. This tool is incredibly useful for front-end developers and designers who want to quickly visualize element boundaries without needing to open developer tools. By applying the style * { outline: 1px solid red; } on demand, it helps in identifying layout issues, inspecting element spacing, and improving CSS debugging efficiency.

Ideal for quick inspection during development, the extension streamlines the process of seeing all HTML elements' borders at a glance. The source code is openly accessible on GitHub for transparency and contribution, making it a lightweight and effective addition to any developer's toolkit.

Is Toggle CSS outline Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Toggle CSS outline requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
