How to set line spacing in css? In fact, there is no direct way to set line spacing in CSS. The line spacing effect can only be achieved by indirectly setting the line height. The larger the line height, the larger the line spacing. This chapter will introduce to you how to attribute the line spacing effect in CSS by setting the line height, so that you can understand how to adjust the line spacing of CSS text. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

First of all, let’s understand what is line height, how to set line height in css, and then set and adjust line spacing.

To put it simply: line height is similar to a single-line book. In a single-line book, there is a space separated by lines. The distance between lines is the line height. Text on a web page is actually written in an invisible line and then appears vertically centered on the line by default. So how to set the row height in css? In css, you can set the line height through the line-height attribute. Let’s briefly introduce the css line-height attribute.

css line-height attribute will affect the layout of the line box. It is used to set the distance (line height) between lines. Negative values are not allowed. When applied to a block-level element, it defines the minimum distance between baselines in that element rather than the maximum distance.

The calculated difference between line-height and font-size (known as "line spacing" in CSS) is divided into two halves and added to the top and bottom of a line of text content. The smallest box that can contain this content is a line box.

Let’s take a look at the possible values of the css line-height attribute:

normal: Set reasonable line spacing, default value.

number: Set a number. This number will be multiplied by the current font size to set the line spacing.

length: Set fixed line spacing.

%: Percent line spacing based on the current font size.

inherit: Specifies that the value of the line-height attribute should be inherited from the parent element.

Note: All browsers support the line-height attribute.

Let’s use examples to introduce how to set and adjust line spacing using the line-height attribute . The following will give examples of how to set line spacing:

1. Use numerical values to Set line spacing

<!DOCTYPE html>
<html>
	<head>
