Deep understanding of the line height properties of css (illustrated)

What is line spacing.

In ancient times we used printing presses to come out text. Every word that is printed is in a separate block.

Line spacing, that is, the legendary control of two lines of text vertical distance. In CSS, Line-height is used to control the vertical distance between rows and rows.

However, the line spacing and half line spacing depends on the line-height in the CSS. So, how to use Line-height?

Default state, the browser uses 1.0-1.2 line-height, which is an initial value. You can define the Line-height property to override the initial value: p{line-height:140%}

There are 5 ways you can define line-height.

1.line-height can be defined as: body{line-height:normal;}

2.line-height can be defined as: Body{line-height:inherit;}

3.line-height can use a percentage of the value body{line-height:120%;}

4.line-height can be defined as a length value (px,em, etc.) body{line-height:25px;}

5.line-height can also be defined as pure numbers, body{line-height:1.2}

Abbreviation Line-height

The 5 types of line-height can be abbreviated in the font attribute. The value of the line-height follows the Font-size value and is separated by a slash, such as:<font-size>/<line-height>

Example: Body{font:100%/normal Arial;, body{font:100%/120% Arial;, body{font:100%/1.2 Arial; , body{font:100%/25px Arial;

Calculate Line-height

Some CSS attributes are inheritable (inherited) and are passed down from a cascade of elements. This is done to facilitate developers and no longer reset values for descendant elements.

It's a bit complicated for line-height inheritance.

1, percentage

2. Length

3 Value: Normal

4 Pure digits

(But the actual application in the Chinese font or in the English font mix, as well as Ie678,xp Win7, row high rules and different, tearful)
