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

If you want to realize the overflow display of ellipses in a single line of text, you should all know to use the text-overflow:ellipsis attribute. Of course, you also need to add the width attribute 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 in the figure:


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 the multi-line text overflow display ellipses, 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 in the figure :


Scope of application:

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 number of lines of text displayed in a block element. 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%);    
}

Applicable scope:
The The method has a wide range of applications, but ellipses will also appear when the text does not exceed the line. This method can be optimized with js.

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.
-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 ellipsis "..." in the case of multi-line text.
