Pesticide is a small CSS stylesheet (available in vanilla CSS, Sass, Less, and Stylus) that draws colored outlines around every element on a page to expose layout bugs. It also ships as a Chrome extension for toggling the debug outlines on any site.
Use cases
- debug css layout bugs
- visualize element outlines on a page
- find what css is causing layout problems
- toggle debug outlines in the browser
- inspect layout without clicking around in dev tools
When to choose
- you are debugging CSS layout issues and want every element's box visible at a glance
- you want a lightweight stylesheet or Chrome extension instead of clicking through dev tools
- you use Sass, Less, or Stylus and want configurable debug flags
When to avoid
- in production - the debug outlines must never ship to users
- you need full inspector features like computed styles or box model editing
