CSS Peek

CSS Peek helps you inspect page elements quickly without opening full DevTools. Click the extension icon, start inspection, and hover over any element on the current page to see a compact floating panel with useful style details. CSS Peek shows: - Tag, ID, and classes - Best selector with a quality hint - Layout details like display, size, and position - Box model values for margin, border, and padding - Typography details like font family, size, weight, and line height - Text and background colors Click an element to copy the best selector to your clipboard. Shift-click an element to copy the full DOM path fallback. CSS Peek is built for developers, solo builders, and frontend work where you need quick visual inspection and a reusable selector fast. No signup. No analytics. No tracking. No external network requests. CSS Peek only runs on the active page after you click the extension. It does not run in the background or collect your data.
