The "CSS Inspector" extension is a handy tool for web developers and designers, available on the Chrome platform. It provides a simple and efficient way to inspect CSS properties of elements on a webpage. By hovering over an element, it outlines the element and displays its CSS properties. This feature is particularly beneficial for those interested in understanding how a webpage is styled and structured.

One of the key features of the CSS Inspector extension is the element outlining functionality. When hovering over elements, it visually highlights them, aiding in identifying boundaries and positioning. Additionally, it displays the HTML Tag properties of the hovered element, facilitating easy identification.
