A Chrome extension for inspecting CSS, colors, typography, and assets from any website.
- Inspect Mode - Hover and click elements to view computed styles, dimensions, and margins
- Distance Lines - Visual dashed lines showing distance from element to its parent (toggleable)
- Rulers - Place horizontal/vertical rulers on the page; drag to reposition; view coordinates in a scrollable list; unit conversion (px/rem)
- Measure Distance - Select two elements to get edge-to-edge distance with visual line and label
- Full-Page Screenshot - Capture entire page; filename includes site and page title; handles sticky/fixed elements
- Color & Typography Extraction - Analyze colors, fonts, and assets from the current page
- Persistent Settings - Toggle states (inspect, distance lines, context menu, continuous inspect) are saved across sessions
- Clean, minimal sidepanel interface
- Intuitive toggles with visual feedback
- Overlay management: all modes automatically disable when sidepanel is closed
- Context menu (info tooltip) can be toggled on/off during inspect
