Debug CSS
When enabled adds outline to all elements on the page, Hold Ctrl and hover to get more detail
# Release notes
In the latest version we have addressed the issue where the extension stopped working after mandatory `manifest_version upgrage` from Google.
also, we have addressed the issue in which user were unable to see the styling for the bottom most element of the page. we have added tooltip feature which gives a basic styles in tooltip itself.
# Debug CSS
A lightweight extension for Google chrome to show outline of all the element exist on page.
while working on web page development the one of the difficult part is to position the element as required and check which element affecting the other one.
This chrome extension allows user to see outline on every element of the page. Hold the keyboard Ctrl button and hover element it will show the element details along with the value.
----------
# Usage
Post installation simply click on the extension icon to turn it On or Off.
If you are a keyboard shortcut lover like me simply hit `Alt+Shift+C ` key to toggle the extension.
----------
# How it works?
This extension works on CSS outline attribute:
add the below code snippet in any CSS of a web page
`
* {
outline: 1px solid red;
}`
The extension does the same the only thing is; it gives different color to different element(s) while the code snippet adds red outline to every element.

Latest reviews
I used Pesticide but the original version cant be installed anymore and the updated replacement is just..not for me (ugly solid colored blocks), or others based on the flood of bad reviews. Looking for alternatives on a new Chrome install, I tried Debug CSS. So far, its awesome. Almost exactly the same as Pesticide in functionality and how it looks when debugging. At least as far as the basic putting boxes on all elements on the page so I can see how things flow together. I had zero problems installing and running it as of April 25, 2025. If you are one of the forlorn Pesticide refugees, give this extension a try. It solid and made me very happy.
This extension is useful but as of March 2025 why does it suddenly need permission to "Read and change all your data on all websites" when it required none previously?
I like this extensions but is it not working anymore? I try on chrome and edge it can't be used
Excellent extension but it recently broke for latest Chrome versions, can't wait for the developer to fix it :) !
Is it no longer available? the most useful extension I have ever used
Giving it a 4 star because I have used this extension for years and now for some reason, it breaks whenever I reload the page. UPDATE!!! It seems this problem only exists on chrome. On firefox it works flawlessly
Great tool but it recently stopped working :( It works very briefly every time I update my browser and then stops working again.
On my latest chrome(133.0.6943.127), it stopped working, sadly
not working in chrome as well please do workable it
I am using Edge browser and this extension stopped working since 18 Feb 2025.
19/02/2025. It don't work in edge browser
Superb, works like a charm
The extension is great. But it would be even better if the dimensions of each box is shown on top of the boxes.
Works but if you aren't seeing the black bar at the bottom telling you what you're hovering on you have to inspect and under styles in the tools uncheck the visibility css attribute. For whatever reason it is defaulted to hidden. Very dumb.
I'm a Mac User. If anyone has an issue that feels not working/ hovering effect not works even Debug CSS active, You have to do a simple thing. Go to manage extension --> Turn ON "Allow access to file URLs".
Very useful, the best extension compared to others that do the "same" job.

Works perfectly on google chrome . Hay developer you should give instructions to press control . otherwise new users might don't know the real usage .

I got here looking for the Pesticide extension recommended by Angela Yu. I love this extension, it helped me A LOT to understand how CSS works, I felt like Neo when he could FINALLY SEE lol =P

Doesn't work on the Mac. Installs but clicking the icon won't enable it, and no combination of keyboard shortcuts will make it work, either. If this extension is made only for Windows, the product description should say so.

If it ain't broke don't fix it. Does the job like the discontinued pesticide did before. Accurate, reliable with a refreshingly new icon. Cheers!
Exactly what I'm looking for, great job - easy and simple :)
