A simple CSS property viewer.
Download Install Compare

CSSViewer is a streamlined Chrome extension originally developed as a Firefox add-on, designed to enable users to easily inspect CSS properties of elements on any webpage. Activate it by clicking the toolbar icon, then hover over elements to instantly view their styles. With open-source code available on GitHub, CSSViewer ensures transparency and privacy—requiring permissions only necessary for functionality without collecting personal data.

This extension supports keyboard shortcuts, local file inspection, and includes features like generating CSS definitions and enhanced positioning. Although occasionally style display may break depending on the website, CSSViewer remains a useful tool for developers, designers, and educators who want quick CSS insights without heavyweight developer tools. Contributions and patches are welcomed to improve functionality further.
