CSS Spy: Chrome Extension for Inspecting CSS Attributes

CSS Spy is a Chrome extension that allows users to inspect computed styles of any single element on the fly. It shows the width, height, and selector name of the element when hovered over. Clicking on the element brings up a popup that displays the common computed styles, making it easy to copy them. The extension also enables users to compare CSS properties of two elements, even from different pages/URLs. With its clean design and convenient features, CSS Spy offers a handy tool for CSS inspection and comparison.

it's works, and is it just what I need :-) Attention! You've to use it on DevTools in Chrome. Press F12 and click the spy button to reach a red symbol. Enjoy!
