The excess part of css is not displayed

In web design, we often encounter a problem: when the content exceeds the width or height of the interface, part of the content cannot be displayed. This is because in most cases, browsers hide out-of-scope content by default to keep the page clean and beautiful. However, sometimes we want the excess part to be displayed. What should we do?

This requires using the CSS overflow attribute. This property indicates how to handle content when it exceeds the bounds. It has four values:

1. visible: Content that exceeds the boundary is displayed and will not be hidden.
2. hidden: Content beyond the boundary is hidden.
3. scroll: Content that exceeds the boundary is displayed, and a scroll bar appears at the same time.
4. auto: Content that exceeds the boundary automatically selects a scroll bar or hides it as needed.

By setting the overflow attribute, the excess content can be displayed. Below we introduce the specific usage in detail.

1. Display horizontal overflow content

When the content width of an element exceeds the width of its container, horizontal overflow will occur. In order to display the excess part, you need to set the following CSS style for the container:

overflow-x: scroll; /*出现水平滚动条*/
whitespace: nowrap; /*禁止换行*/

This way, when the width of the container is not enough, the excess content can be automatically scrolled and displayed.

2. Display vertical overflow content

When the content height of an element exceeds the height of its container, vertical overflow will occur. In order to display the excess part, you need to set the following CSS style to the container:

overflow-y: scroll; /*出现垂直滚动条*/

This will allow the excess content to automatically scroll when the height of the container is not high enough.

3. Display both horizontal and vertical overflow content at the same time

If an element has both horizontal and vertical overflow, you need to combine the above two methods. The specific method is as follows:

overflow: scroll; /*同时出现水平、垂直滚动条*/

In this way, all excess content can be displayed.

4. Let the overflow content overflow the container

Sometimes, the page design requires the excess content to be displayed. At this time, we can use CSS "overflow clipping" to achieve this. The specific method is:

overflow: visible; /*允许容器外的内容显示出来*/

In this way, all the excess content can be displayed without any restrictions.

It should be noted that when using overflow cropping, the excess content may cover other elements, affecting the beauty of the page. Therefore, special care is required when using it.

To summarize, by setting the overflow property of CSS, you can display part of the content beyond the container, which is very useful in page design. Different attribute values ​​can meet different needs, and at the same time, attention should be paid to the impact on the aesthetics of the page. I hope that through the introduction of this article, readers can better master the use of overflow attributes and bring more beauty and functionality to page design.
