I used Pesticide by @mrmrs for many years to simple outline all elements on a web page. It’s super useful. “Kill your CSS layout bugs. Without 2000 clicks in Chrome Dev Tools.”

I still want a super quick way of seeing every single element on the page to show me where its outline is. With different colors, to tell stuff apart.

I decided to make my own Chrome extension to do this now. It’s called CSS Outline Debugger and works the same way as Pesticide, but I’m planning to add more features in the future.
