CSS Scan

Overview

CSS Scan is a browser extension that lets you check and copy CSS from any element on any website. It replaces the need to open browser Dev Tools and hunt through Inspect Element panels.

Designed for front-end developers, designers, and anyone who works with CSS, CSS Scan shows the active styles of any element you hover over in real time and copies all rules — including pseudo-classes, media queries, and child elements — with a single click. It runs hundreds of real-time optimizations to remove duplicated, overridden, or longhand CSS, outputting only clean, readable code.

Key Benefits

• Copy the full CSS of any element — including :hover, :before, :after, :focus, media queries, and child elements — with one click.
• Optimizes CSS output automatically by stripping unuseful, duplicated, overridden, and longhand rules, so you only see active styles.
• Works on every website regardless of framework (WordPress, Wix, Squarespace, Shopify, React) and even works offline.
• Navigate through the DOM tree using arrow keys to inspect parents, siblings, and child elements when hovering over the wrong element.
• Export complete components (HTML + CSS) to CodePen snippets saved to the cloud for reuse across projects.
• Convert thousands of elements from regular CSS to Tailwind CSS utility classes with a single click using the optional Tailwind converter.

How It Works

You click the CSS Scan extension icon on your browser toolbar to activate it on any website. Hover over any element on the page, and CSS Scan instantly displays its computed CSS in a clean overlay window. Click the element to copy its CSS to your clipboard, or press the space bar to pin the window open, edit the CSS values in real time, or export the component to CodePen.

Use Cases

• Front-end developers learning new CSS techniques — inspect and copy the styling of design patterns they admire on live sites.
• Freelance web designers — extract and reuse entire UI components from their favorite websites without manually re-creating every rule.
• Tailwind CSS adopters — convert existing classic-CSS elements from any website to Tailwind utility classes in one click, saving months of migration work.
• UI engineers debugging layout issues — hover to see only the final computed styles instead of wading through inherited and overridden rules in Dev Tools.
• Design students building component libraries — export HTML and CSS snippets to CodePen to assemble and share a personal collection of reusable elements.

Why Choose This Product

CSS Scan is best suited for front-end developers and designers who inspect and copy CSS many times per day and want to eliminate the friction of browser Dev Tools. The license is a one-time, lifetime deal — no subscription. It is available on Chrome, Firefox, Safari, and Edge, but not on Internet Explorer.
