Description
Inspect CSS margin, padding, gap, dimensions, typography, and layout visually on any webpage. Built by oneDesigns. See the CSS behind every layout—directly on the page. SpaceLens is a privacy-first visual inspector for designers, developers, and QA teams. Activate it on any standard webpage to reveal margins, padding, gaps, dimensions, typography, colors, and layout properties without leaving the page. Use SpaceLens to: • Visualize margin, padding, and gap values • Inspect element dimensions and computed presentation styles • Compare two elements with Shift+Click measurements • Temporarily edit selected CSS properties and preview changes live • Copy useful CSS for your own development workflow • Switch between All, Margin, Padding, and Gap inspection modes Built for focused design and frontend debugging: • Runs only after you click the SpaceLens toolbar icon • Uses temporary access to the active tab—no broad website access • Processes inspected page information locally in your browser • No analytics, telemetry, advertising, accounts, or remote code • Temporary edits disappear when the page is refreshed SpaceLens works on ordinary HTTP and HTTPS webpages. Chrome-protected pages, including chrome:// pages and the Chrome Web Store, cannot be inspected. Developed and maintained by oneDesigns.
