CSS Scan

About CSS Scan

CSS Scan is a browser extension for inspecting and copying CSS from any element on a webpage. Hovering over an element displays its active CSS rules directly, without opening browser developer tools, and a single click copies the code. The extension filters out unused, duplicated, overridden, and longhand CSS, and it preserves original measurement units (such as % and em) rather than converting them to pixels. It also captures pseudo-classes, pseudo-elements, media queries, and child elements in a single copy action, and includes a DOM navigation feature using arrow keys to select parent, sibling, or child elements.

Additional features include an option to convert copied CSS into Tailwind CSS utility classes (including @apply for custom styles), an editable CSS preview that updates in real time, and the ability to export an element's HTML and CSS to CodePen as a saved snippet. The tool works on any website regardless of the underlying framework, theme, or platform, including WordPress, Wix, Squarespace, Shopify, and React sites, and it functions offline once installed.

CSS Scan is aimed at web developers and designers who need to inspect and reuse CSS styling from existing websites. It is available as a browser extension for Chrome, Firefox, Safari, and Edge, sold as a one-time lifetime license priced at $120 (listed at a discounted $69 at time of writing), with each license usable on up to 3 browsers simultaneously. A free demo is available for use on the product's own website on desktop.
