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
