CSS implementation method to realize single-line and multi-line text overflow and display ellipses

This article mainly introduces the implementation method of CSS to realize single-line and multi-line text overflow display ellipsis. It has certain reference value. Now I share it with you. Friends in need can refer to it.

If it is implemented Students should all know that the overflow of a single line of text displays an ellipsis using the text-overflow:ellipsis attribute. Of course, the width attribute needs to be added to be compatible with partial browsing.

1. Single line overflow

1, a single line overflows, the excess part is displayed...or intercepted. The premise must have width.
CSS: {width:xxpx;overflow:hidden;white-space:nowrap;text-overflow:ellipsis;}, intercepted as clip;
Implementation code:

width:300px;    
overflow: hidden;    
text-overflow:ellipsis;    
whitewhite-space: nowrap;

The effect is as shown:

But this attribute only supports the overflow display of ellipsis in a single line of text. What if we want to implement the overflow display of ellipsis in multi-line text.
Next, let’s focus on displaying ellipses when overflowing multi-line text, as follows.

2. Multi-line overflow

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

Implementation method:

display: -webkit-box;    
-webkit-box-orient: vertical;    
-webkit-line-clamp: 3;    
overflow: hidden;

The effect is as shown:

Applicable scope:

Due to the use of WebKit's CSS extended attributes, this method is suitable for WebKit browsers and mobile terminals;
Note:
1.-webkit-line-clamp is used to limit the display of one block element The number of lines of text. In order to achieve this effect, it needs to be combined with other WebKit properties. Commonly combined attributes:
2.display: -webkit-box; must be combined to display the object as a flexible box model.
3.-webkit-box-orient must be combined with the attribute to set or retrieve the arrangement of the child elements of the flex box object.

Implementation method:

p{position: relative; line-height: 20px; max-height: 40px;overflow: hidden;}    
p::after{content: "..."; position: absolute; bottombottom: 0; rightright: 0; padding-left: 40px;    
background: -webkit-linear-gradient(left, transparent, #fff 55%);    
background: -o-linear-gradient(rightright, transparent, #fff 55%);    
background: -moz-linear-gradient(rightright, transparent, #fff 55%);    
background: linear-gradient(to rightright, transparent, #fff 55%);    
}

Scope of application:
This method has a wide range of applications, but ellipses will also appear when the text does not exceed the line, and can be combined with js Optimize this method.

Note:

1. Set height to an integer multiple of line-height to prevent excess text from being exposed.
2. Add a gradient background to p::after to prevent only half of the text from being displayed.
3. Since ie6-7 does not display content 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.

Script House editor added:

ie core browser must define line-height and height, -webkit-line-clamp means a few lines, For example

line-height: 20px;

max-height: 40px;

display: -webkit-box;

-webkit- box-orient: vertical;

-webkit-line-clamp: 2;

overflow: hidden;

##-webkit-line-clamp

-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 properties:
display: -webkit-box; must be combined to display the object as a flexible box model.
