GetCSS

Extract final computed CSS that differs from browser defaults

GetCSS extracts the final computed CSS for any web page, showing only the styles that actually differ from browser defaults. Instead of wading through thousands of default properties, GetCSS gives you a clean, grouped output of just the CSS that was applied — whether from stylesheets, inline styles, or JavaScript. How it works: 1. Navigate to any web page 2. Click the GetCSS icon in your toolbar 3. Click "Extract CSS" 4. Copy the result with one click Features: • Shows only non-default styles — filters out browser UA stylesheet noise • Groups elements with identical styles under shared selectors • "Appearance only" mode to see just visual properties (colors, fonts, borders) without layout noise • "Visible only" mode to skip hidden elements • Live progress bar for large pages • Readable output with tag, class, and ID selectors • One-click copy to clipboard • Works entirely offline — no data sent anywhere Use cases: • Quickly audit what CSS is actually in use on a page • Reverse-engineer styles from any website • Debug computed values vs. what you expect • Export a page's effective styles for reference
