css exceeds part display

Overflow handling in CSS refers to how to handle the situation when the content within an element exceeds the size of their container. Normally, the browser will automatically adjust the size and position of the content within the container based on the size of the container, but sometimes we want to be able to control the display effect when the content exceeds the container. This article will introduce techniques and methods on how to handle excess display in CSS.

1. Overflow attribute

In CSS, you can use the overflow attribute to handle the overflow of content in the container. This attribute has the following four values:

1. visible: default value. Allows content to overflow the container and be displayed outside the container.
2. hidden: Indicates that the content will be hidden outside the container. In other words, this value cuts off the overflow content, making it invisible.
3. scroll: Indicates that the content will scroll within the container. This value creates scroll bars within the container, allowing content to be scrolled.
4. auto: If the overflow content can fit in the container, no processing will be done. If the overflow content cannot fit, scroll bars will be displayed.

2. The text-overflow attribute

The text-overflow attribute can control how to handle overflow text. It only applies to inline block-level elements or inline elements, because only these elements can Complete automatic line wrapping of text.

text-overflow has the following three values:

1. clip: default value. When the text exceeds the container, it will be cropped directly.
2. ellipsis: When text exceeds the container, it will be represented by ellipses.
3. string: Custom ellipses. You can use this property to customize the ellipses for any string.

3. white-space attribute

The white-space attribute can control whether the text is automatically wrapped, whether the overflow text display ignores "spaces", and how to handle "spaces".

This attribute has the following three values:

1. normal: default value. Indicates that the text will be automatically wrapped and extra "spaces" will be ignored.
2. nowrap: Indicates that the text will not wrap automatically. When the text exceeds the width of the container, it will directly overflow the container.
3. pre-wrap: Indicates that "spaces" are retained, but lines can be automatically wrapped.

4. Multi-column layout column-layout

Using CSS's multi-column layout, the content in the container can be divided into multiple columns for display, avoiding the situation where a single column of content exceeds the container. .

You can use the column-count attribute to define the number of columns in multiple columns; use column-gap to define the distance between columns; use column-rule to define the border style between columns, etc.

5. Force inline elements (such as pictures) to be arranged horizontally

Some elements are block-level elements by default, such as pictures (), and they will occupy a separate line. If we want to put multiple images on the same line, we can use display:inline-block to convert these elements into inline elements.
