csstext overflow

When we are doing web front-end development, we usually get the article title and then display it line by line. But when the title is too long, it will cause line breaks. Also, when displaying part of the text information, it would be too cumbersome to display all of it, which would lead to a poor web experience. Although we can use overflow:hidden to hide characters that exceed the width. But the ending always seems a bit stiff. It is also not conducive to letting the user know that there are still undisplayed characters later. The best way is to replace the extra characters with ellipses.

In this chapter, we will give you a detailed introduction to how CSS makes the overflow part of the text display ellipses. I hope to be helpful.

1: A single line of text overflows and displays an ellipsis... (mostly the excess part of the title displays an ellipsis...)

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title>CSS如何使文本溢出部分显示省略号？单行超出</title>
		<style>
			*{margin: 0px;padding: 0px;}
			.box{width: 300px;height: 500px;margin: 50px auto;}
			.overflow{
				width:220px;
				overflow:hidden;
				white-space: nowrap;
				text-overflow: ellipsis;
				-o-text-overflow:ellipsis;
			}
		</style>
	</head>
	<body>
		<div class="box">
			<p>
				css 实现单行文本超出长度显示省略号
			</p>
			<p class="overflow">
				css 实现单行文本超出长度显示省略号
			</p>
		</div>
	</body>
</html>

Rendering of the above code As follows:

Among them, white-space: nowrap; means that the text will not wrap and continue on the same line until it encounters a label;

overflow: hidden; Do not display content that exceeds the object size, that is, hide the excess part;

text-overflow: ellipsis; When the text object overflows, it is displayed..., of course, you can also set the attribute to clip Dots are not displayed;

-o-text-overflow: In order to be compatible with the opera browser;

2: Multi-line text overflow displays ellipses...

1. Directly use css attribute settings (only the -webkit kernel has an effect)

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title>CSS如何使文本溢出部分显示省略号？多行超出</title>
		<style>
			*{margin: 0px;padding: 0px;}
			.box{
				width: 280px;
				height: 62px;
				margin: 50px auto;
				overflow: hidden;
				text-overflow: ellipsis;
				display: -webkit-box;
				-webkit-line-clamp: 3;
				-webkit-box-orient: vertical;
			}
		</style>	
	</head>
	<body>
		<div class="box">
			css 实现多行文本超出长度显示省略号，css 实现多行文本超出长度显示省略号，
			css 实现多行文本超出长度显示省略号
		</div>
	</body>
</html>

The rendering of the above code is as follows:

Among them, Most mobile browsers are based on WebKit core, so this method is suitable for mobile terminals;

-webkit-line-clamp is used to limit the number of lines of text displayed in a block element. This is a different Unsupported WebKit property, which does not appear in the CSS draft specification;

display: -webkit-box displays the object as a flexible box model;

-webkit-box- orient sets or retrieves the arrangement of the child elements of the flex box object;

text-overflow: ellipsis is used for multi-line text, using the ellipsis "..." to hide the text that exceeds the range.

2. Using pseudo-classes

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title>CSS如何使文本溢出部分显示省略号？多行超出</title>
		<style>
			*{margin: 0px;padding: 0px;}
			.box{
				width: 280px;
				height: 62px;
				margin: 50px auto;
				overflow: hidden;
				text-overflow: ellipsis;
				display: -webkit-box;
				-webkit-line-clamp: 3;
				-webkit-box-orient: vertical;
			}
			p{position: relative; line-height: 20px; max-height: 40px;overflow: hidden;}
			p::after{
				content: "..."; position: absolute; bottom: 0; right: 0; padding-left: 40px;
				background: -webkit-linear-gradient(left, transparent, #fff 55%);
				background: -o-linear-gradient(right, transparent, #fff 55%);
				background: -moz-linear-gradient(right, transparent, #fff 55%);
				background: linear-gradient(to right, transparent, #fff 55%);
			}
		</style>	
	</head>
	<body>
		<div class="box">
		  <p>
		      css 实现多行文本超出长度显示省略号，
		      css 实现多行文本超出长度显示省略号，
		      css 实现多行文本超出长度显示省略号
		 </p>
		</div>
	</body>
</html>

The rendering of the above code is as follows:

This method has a wide range of applications, but the text does not exceed Ellipses will also appear in the case of rows, and this method can be optimized with js.

Set height to an integer multiple of line-height to prevent excess text from being exposed. Adding a gradient background to p::after prevents only half of the text from being displayed. Since ie6-7 does not display content, you need to add tags to be compatible with ie6-7 (such as: ...); to be compatible with ie8, you need to replace ::after with :after.

3. Use absolute positioning and padding; (cross-browser solution)

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title>CSS如何使文本溢出部分显示省略号？多行超出</title>
		<style>
			*{margin: 0px;padding: 0px;}
			.box{width: 300px;height: 500px;margin: 50px auto;}
			.con{
			  position: relative;
			  height: 40px;
			  width: 250px;
			  line-height: 20px;
			  overflow: hidden;
			  padding-right: 12px;
			}
			.t{
			  position: absolute;
			  right: 0;
			  bottom: 0;
			}
		</style>	
	</head>
	<body>
		<div class="box">
			 <p class="con">
			 	css 实现多行文本超出长度显示省略号，
			 	css 实现多行文本超出长度显示省略号，
			 	css 实现多行文本超出长度显示省略号。
			 	<span class="t">...</span>
			 </p>
		</div>
	</body>
</html>

Rendering of the above code:

This The principle of the method is: first embed a ... in the element containing text, and then leave an ellipsis... position (padding-right) on the right side of the element containing text, Finally, use absolute positioning to position the ellipsis... to the padding-right area on the right (lower right corner).
