Using CSS to implement text truncation in HTML

This time I will bring you how to use CSS to truncate text in HTML, and what are the precautions for using CSS to truncate text in HTML. The following is a practical case, let's take a look. Single line text truncation

text-overflow

Text overflow we often use should be text-overflow: ellipsis. I believe everyone is familiar with it. It only takes a few steps. Single line text truncation can be achieved with just one line of code.

div {  white-space: nowrap;  overflow: hidden;  text-overflow: ellipsis;
}

Attributes are natively supported by browsers and have good compatibility with major browsers. The disadvantage is that it only supports single-line text truncation and does not support multi-line text truncation.

Applicable scenarios: Single-line text truncation is the easiest to implement and has the best effect, so you can use it with confidence.

If it is a multi-line text interception effect, it is not so easy to implement.

-webkit-line-clamp implements

through the -webkit-line-clamp attribute. The specific method is as follows:

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

It needs to be used in conjunction with display, -webkit-box-orient and overflow:

display: -webkit-box; must be combined with the properties to use the object as elastic Telescopic

Box model

display. -webkit-box-orient; An attribute that must be combined to set or retrieve the arrangement of the sub-elements of the flex box object.

text-overflow: ellipsis; Optional attribute, which can be used for multiple purposes. In the case of line text, use the ellipsis "..." to hide the text beyond the range.

From the effect point of view, its advantages are:

Responsive truncation, adjustment according to different widths

The ellipsis will be displayed only when the text exceeds the range, otherwise the ellipsis will not be displayed

Browser native implementation, so the ellipsis position is displayed just right

But the disadvantage is also very direct, because -webkit-line-clamp is an unstandardized attribute and it does not appear in the CSS specification draft. In other words, only browsers with webkit core support this attribute. Browsers such as Firefox and IE do not support this attribute, and the browser compatibility is not good.

Usage scenarios: Mostly used for mobile pages, because mobile device browsers are more based on the webkit kernel. In addition to poor compatibility, the truncation effect is good.
