Image from store Debug CSS
Description from store # 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. ---------- # Other work and repository [A lightweight customizable plugin for jQuery to show horizontal length in form of vertical progress bar.](https://github.com/pranayjoshicse/VerLim.js) [listed on jqueryscript.net](https://www.jqueryscript.net/other/Simple-Custom-Reading-Indicator-with-jQuery-VerLim-js.html) [Demo](https://www.jqueryscript.net/demo/Simple-Custom-Reading-Indicator-with-jQuery-VerLim-js/) ---------- # More about me [twitter.](https://twitter.com/pranayjoshicse) [about me.](https://about.me/pranayjoshi)

  • (2021-07-15, v:1.0) Ryan Bott: Blue borders can't be seen on blue backgrounds
    Hey there, Great extension! It has been helpful while working on design issues. I've noticed that it's not as helpful when I have a container with a blue background and it draws blue borders around it. It might be nice to have a few different color themes to choose from or be able to customize the indicator colors. Thanks!
  • (2021-04-27, v:1.0) Sampad Singha: Not working on local file
    Hi. I'm facing problem. The extension works fine when I try on a global website like facebook or youtube or any other website. But when I try to use it on a local file that I'm currently working on, it does nothing.

  • (2020-11-17, v:1.0) Jackson Hsieh: It does not work on the file I open from my computer
    It works on websites online but the HTML/CSS/JS files I open from my computer with chrome does not show the outline. How to make it work?
  • (2020-11-13, v:1.0) mjs28s: Sometimes page elements on certain websites covers the information banner
    Example - www.seekingalpha.com, many of their elements cover up the hover / info bar. Some images on yahoo.com do the same thing. Is it possible to add some sort of sorting order so that the hoover bar is always on top?
