CSS controls single-line or multi-line text beyond the display ellipsis

1. Single Line Text

Use the text-overflow:ellipsis property

text-overflow: clip|ellipsis|string;

clip: Trim the text.

ellipsis: Displays ellipses to represent trimmed text.

string: Use the given string to represent the trimmed text.

Example:

css:

p{
	overflow: hidden;/*The excess part is hidden*/
	text-overflow:ellipsis;/* Display ellipsis in excess */
	white-space: nowrap;/*Specifies that the text in the paragraph does not wrap*/
	width: 250px;/*It needs to be used with width*/
	border: 1px solid red;
	font-size: 30px;
}

html:　　

<p>Single-line text exceeding part displays ellipsis I am mdzz</p>

2. Multi-line text displays ellipsis

　　display: -webkit-box;
　　-webkit-box-orient: vertical;
　　-webkit-line-clamp: 3;
　　overflow: hidden;
　　width: 250px;
　　border: 1px solid red;
　　font-size: 30px;　

Because the CSS extension property of WebKit is used, 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 combine other WebKit properties. Common binding properties:
2. display: -webkit-box; A property that must be combined to display the object as a flexible box model.
3. -webkit-box-orient A property that must be combined to set or retrieve the arrangement of the child elements of the flexbox object.

Scope of application:
This method has a wide range of applications, but ellipsis will also appear when the text does not exceed the line. This method can be optimized in combination with js.

Note:

　　1. Set the height to an integer multiple of line-height to prevent the excess text from being exposed.

　　

 

　　2.

Add a gradient background to p::after to avoid half of the text.

 

　　3. Since ie6-7 does not display content content, add tags to be compatible with ie6-7 (eg: <span>…<span/>); for compatibility with ie8, replace ::after with :after.

Applicable methods for compatibility:

Note:

This method needs to be adjusted according to your own font size and the width you set yourself. Although it is compatible (pro-test), it is still a bit troublesome. But it is possible to display the ellipsis in the middle in the last row.
