You know what sucks? Desperately trying to figure out how you broke your html layout, only to discover hours later that you had an invisible element or padding or a margin that was quietly ruining everything. Pesticide to the rescue! Pesticide is a very simple Chrome extension that does just one thing – it outlines all of your elements. That’s it.

I have a thing for simple tools that do one thing and do it well, and Pesticide is just that. No screwing around with settings, no trying to remember how to activate it, you just click the little bug icon beside your omnibox to┬áturn it on and click it again to turn it off. Simple is just what you need when you’re fighting with your layout. Try it, you just might like it!
