Cisster

Inspect page elements and copy focused HTML/CSS snippets from the current tab.

Cisster is a lightweight CSS Spy Mode extension for developers and designers who need to inspect, extract, and reuse page styling quickly. Turn on Spy Mode from the extension popup or with Ctrl+Shift+S, hover over any element on the current page, and Cisster highlights its box model while showing useful element details. Click to open the in-page copy menu and choose the extraction style you need, including HTML, CSS, combined HTML/CSS, scoped component output, tokenized variables, and selector-based snippets. Cisster is built for focused front-end inspection without accounts, telemetry, or background data collection. It only runs on the active tab when you turn Spy Mode on.
