# 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
- (2025-04-25) Joshua Ford: 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.
- (2025-03-30) Vishwanath Veerni: 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?
- (2025-03-07) Adam Abdillah: I like this extensions but is it not working anymore? I try on chrome and edge it can't be used
- (2025-02-27) Lethargic: Excellent extension but it recently broke for latest Chrome versions, can't wait for the developer to fix it :) !
- (2025-02-25) AlexSearch: Is it no longer available? the most useful extension I have ever used
- (2025-02-25) Charles: 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
- (2025-02-21) Bee: Great tool but it recently stopped working :( It works very briefly every time I update my browser and then stops working again.

- (2024-11-03) Arthur Marchand: Superb, works like a charm
- (2024-09-21) Bhupen Pal: The extension is great. But it would be even better if the dimensions of each box is shown on top of the boxes.
- (2024-07-23) Speedx77x2: 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.
- (2024-04-05) Senura Chamod: 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".
- (2023-03-23) Guilherme Santos: Very useful, the best extension compared to others that do the "same" job.

- (2021-04-28) Bob Flisser: 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.
