How to use CSS to make single-line or multi-line text overflow and display ellipsis

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 some browsing.

Implementation method:

overflow: hidden;
text-overflow:ellipsis;
white-space: nowrap;

The effect is as shown:

But this attribute only supports a single line The overflow of text displays ellipses. What if we want to implement multi-line text overflow and display ellipses.

Next, let’s focus on the multi-line text overflow display ellipses, as follows.

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

2. display: -webkit-box; Attributes that 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; 
    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%);
    }

The effect is as shown:

## Scope of application: This 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 add: Replace :after with :after.
