How to use CSS to turn excess text into ellipses

CSS is a very important technology in front-end development. It plays a very important role in web design and style control. Text that goes beyond hiding and becomes an ellipsis is an important skill in CSS technology. In this article, I will show you how to use CSS to turn text beyond hidden into an ellipsis.

1. Text exceeds hiding

When the text on the page exceeds a certain range, sometimes it is necessary to hide it and only display part of the text. At this time, we can use the overflow property in CSS to achieve this.

The overflow attribute can be used to control how the content inside an element is handled when it exceeds the container area. Common attribute values ​​include hidden, visible, auto and scroll.

When we set overflow:hidden, the content beyond the container area will be hidden.

For example, we can set overflow:hidden for a div container in CSS, and then insert a lot of text. These texts will exceed the scope of the container, but are hidden, and only the content within the container can be seen. part of the text. This achieves the beyond-hiding of text.

2. Implementation of ellipses

The text beyond hiding is just the hidden text, but in some cases just hiding the text is not enough, we need to show the user the excess text information. At this time, you need to add an ellipsis to the end of the hidden text. In this way, users can know the omitted text information without affecting the overall layout of the page.

In CSS, we can use the text-overflow attribute to add ellipses. The text-overflow attribute can be used to control how out-of-range text is displayed. The usual value is ellipsis, which means that ellipses are used to replace out-of-range text.

However, it should be noted that the text-overflow attribute will only take effect when the following three conditions are met at the same time:

1. The white-space attribute of the element must be set to nowrap or pre;

2. The overflow attribute of the element must be set to hidden or scroll;

3. The width or height attribute of the element must be set to a fixed value.

On the premise that the above three conditions are met, we can use the text-overflow attribute to turn out-of-range text into ellipses.

For example, we can hide the text in a div container and use the text-overflow attribute to add ellipses:

div{
overflow: hidden;
text- overflow: ellipsis;
white-space: nowrap;
width: 200px;
}

In this example, we hide the text in a div container and limit the content of the container The width is 200 pixels, and the text-overflow property is used to replace the out-of-range text with ellipses.

3. Conclusion

The use of hidden text and ellipses are common techniques in CSS, which play a very important role in the design and layout of web pages. However, when using it, you need to pay attention to the settings of various attributes and conditions to achieve the expected results. Hope this article helps you!
