it really works
I've been using this for front-end web development for a year now and it is so helpful to figure out sizing, padding, margins, and more in CSS land. I often take screenshots of components with Pesticide on to demonstrate the inconsistencies in UI. I love how easy it is to toggle on and off up in the chrome extensions tool bar.
Amazing
A must have extension for web development. It helps a lot to debug the elements in the screen to ensure everything is positioned and sized correctly.
I had a problem with this extension where it only worked on online websites. You will have to Allow access to files URLs by going into its settings, Only then it will work on your local projects. I hope I've helped!
The extension is not working on an HTML/CSS template located in the browser.
works perfectly
it doesn't work in pc chrome why? any solution for this matter please help me .
did not like the way the solution was written.
great extension! So useful and easy to use. A keyboard shortcut option would be nice for hardcore css-debugger :)
