Easy way to do CSS debug

Hanging out today on the Internet in search of something interesting, stumbled upon such a simple (and equally remarkable in its simplicity) way of finding a “problem” in the layout.

CSS

* { outline: 2px dotted red; }
* * { outline: 2px dotted green; }
* * * { outline: 2px dotted orange; }
* * * * { outline: 2px dotted blue; }
* * * * * { outline: 1px solid red; }
* * * * * * { outline: 1px solid green; }
* * * * * * * { outline: 1px solid orange; }
* * * * * * * * { outline: 1px solid blue; }


The color, type and size of the stroke can be chosen by everyone.
