The content of this article is about what does list-style mean? A detailed explanation of list-style style attributes has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

1. The function and use of list-style

list-style is to set the style of list li. For example, li is preceded by Arabic numerals, dots, solid circles, pictures, hollow circles, lowercase English letters, uppercase English letters, traditional Armenian numerals, etc.

2. Grammar

1. Grammar:

list-style : list-style-image || list-style-position || list -style-type

We know that HTML syntax stipulates that li must be used within ul or ol, so for ul or ol, you can set list-style-image to introduce pictures as the front layout material of li. But usually this method is not used to set the front image material of li during div css layout. Usually, the background image is set directly to li, which is better compatible and easier to control.

We use the list-style-type attribute, which is mostly list-style, to set the default front style of li.

2. Values and explanations of list-style-type

You can test it yourself to see the effects of various values.

3. General layout practices

Usually when laying out a web page, you need to start CSS Remove the list-style style of the three lists ul ol li, also to be compatible with major browsers, and cancel the default list-style of the list tag.

Cancel the list-style style code of ul li ol:

ul,ol,li{list-style:none}

In the web page, you need to set a dot in front of the list, and then set the Background background image for li.

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>ul li布局实例</title>
<style>
ul, ol, li {list-style: none;margin:0; padding:0;normal;font:14px/24px Arial}
</style>

##2. Explanation

Remove li ul ol above The default list-style style of the three sets mragin and padding to 0, font size to 14px, and line height to 24px. Why not use li's own list-style-type to set the dot effect?

This is because there are certain differences between different browsers to avoid different dot effects and different distances from the left, so the list-style style is uniformly canceled and the background style is reused for layout implementation.
