This time I will bring you the CSS extension effect of WebKit. What are the precautions for using CSS WebKit. The following is a practical case, let’s take a look.

-webkit-line-clamp is an unsupported WebKit property. It does not appear in the CSS draft specification, but we often use this parameter in text overflow

- webkit-line-clamp

Overview:

-webkit-line-clamp is an unsupported WebKit property that does not appear in the CSS draft specification.

Limit the number of lines of text displayed in a block element. In order to achieve this effect, it needs to be combined with other foreign WebKit properties. Commonly combined attributes:

display: -webkit-box; Attributes that must be combined to display the object as an elastic scaling box model.
-webkit-box-orient must be combined with the attribute to set or retrieve the arrangement of the child elements of the flex box object.
text-overflow can be used to hide out-of-range text with the ellipses "..." in the case of multi-line text.

Syntax:

-webkit-line-clamp:
Default value: ? indicates unclear;
Applies to: Block elements
Inheritance: None
Animation: No
Calculated value: Specified value
Value:

:
Block The number of lines of text displayed by the element.
* There may be description errors and changes in the new attributes of CSS3. They are for reference only and will be continuously updated.

Compatibility:

?Unclear

Example code: css overflow hidden

<!DOCTYPE HTML>
<html>
<head>
    <meta charset="utf-8">
    <title>无标题文档</title>
	<style type="text/css">
.jb51{
	overflow : hidden;
	text-overflow: ellipsis;
	display: -webkit-box;
	-webkit-line-clamp: 2;
	-webkit-box-orient: vertical;
	line-height: 20px;
  max-height:40px;
  width:500px;
	height: 200px;
}
    </style>
</head>
 
<body>
<p class="jb51">
 static：对象遵循常规流。top，right，bottom，left等属性不会被应用。 relative： 对象遵循常规流，并且参照自身在常规流中的位置通过top，right，bottom，left属性进行偏移时不影响常规流中的任何元素。 absolute：对象脱离常规流，使用top，right，bottom，left等属性进行绝对定位，盒子的偏移位置不影响常规流中的任何元素，其margin不与其他任何margin折叠。fixed：对象脱离常规流，使用top，right，bottom，left等属性以窗口为参考点进行定位，当出现滚动条时，对象不会随着滚动。center：对象脱离常规流，使用top，right，bottom，left等属性指定盒子的位置或尺寸大小。盒子在其包含容器垂直水平居中。盒子的偏移位置不影响常规流中的任何元素，其margin不与其他任何margin折叠。（CSS3）page：盒子的位置计算参照absolute。盒子在分页媒体或者区域块内，盒子的包含块始终是初始包含块，否则取决于每个absolute模式。（CSS3） sticky： 对象在常态时遵循常规流。它就像是 relative 和 fixed 的合体，当在屏幕中时按常规流排版，当卷动到屏幕外时则表现如fixed。该属性的表现是现实中你见到的吸附效果。（CSS3）* CSS3新增属性可能存在描述错误及变更，仅供参考，持续更新

Core code

overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;
-webkit-line-clamp: 2;
-webkit-box-orient: vertical;

If your label is in English, English It will not wrap automatically, so you need to let it wrap automatically by adding the following code

word-wrap:break-word;
word-break:break-all;

You can also use the plug-in

clamp.js
