A piece of clever CSS debug code _css/html

The idea is very simple, the code is very concise, the effect is also good, very useful (this high-grade dongdong IE nature is not recognized).

Copy Code code as follows:

* {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} * * * * * * * * * * * * *

It is easy to understand, with different colors and different styles of outline to mark the level of relations.
