Design Inspector Pro is a powerful developer and designer tool that injects a real-time inspection panel into any webpage — no DevTools required. 🎨 Pixel-Perfect Color Picker Hover over any pixel to see its exact Hex, RGB, and HSL values with an 11×11 magnified zoom lens. Click to copy instantly. 🔤 Typography Inspector Instantly reveal font family, size, weight, line-height, and letter-spacing of any text element on the page. </> CSS Extractor Extract computed CSS properties including display, position, flexbox/grid, padding, margin, borders, and shadows — then export as CSS, JSON, or Design Tokens. 🎯 Smart Element Locking Hover to preview any element live, click to lock the panel. Press Esc to release and move on. 🧩 Full-Page Palette Scanner Crawls every element on the page and extracts all unique colors into a clean, copyable swatch grid. 🏗️ Design System Generator One click generates a complete design system snapshot — color palette, type scale, and spacing scale — extracted directly from the live page. 📤 Multi-Format Export Export styles as CSS, JSON, or W3C Design Tokens for seamless handoff to your workflow. 🌓 Dark / Light Theme Ships in dark mode with a persistent theme toggle. Built with Vanilla JS, zero dependencies, and Shadow DOM isolation so the panel never conflicts with the page it inspects.
