Hover to inspect
Move across a page and see selector, size, color, typography, spacing, layout, and useful computed declarations.
Chrome CSS viewer
View the CSS you actually need.
CascadePeek turns Chrome into a focused CSS viewer for frontend developers: hover an element, read the relevant styles, pin the result, and copy clean output.
Pin the panel
Freeze one element while you compare siblings, inspect children, or copy CSS without losing your place.
Copy clean snippets
Copy focused CSS or HTML instead of sorting through a long computed style dump.
Edit in context
Use Pro to test small CSS changes directly on the page before moving them into your codebase.
