Can Text in css support height:
This section describes a concept that may be misleading.
That is, when the height of a div is not set, many people may think that its height is opened by internal text. Is that true? The following code is used for verification, the code example is as follows:

<! DOCTYPE html>  
We can see that there is no demonstration result, and the height is not supported. Here we will discuss the line-height knowledge.
For more information about line-height, see the line-height attribute introduction section.
