column-count CSS 属性将一个元素的内容分成指定数量的列。

{{InteractiveExample("CSS Demo: column-count")}}

```css interactive-example-choice column-count: 2;


```css interactive-example-choice
column-count: 3;

```css interactive-example-choice column-count: 4;


```css interactive-example-choice
column-count: auto;
column-width: 8rem;

```html interactive-example

London. Michaelmas term lately over, and the Lord Chancellor sitting in Lincoln's Inn Hall. Implacable November weather. As much mud in the streets as if the waters had but newly retired from the face of the earth, and it would not be wonderful to meet a Megalosaurus, forty feet long or so, waddling like an elephantine lizard up Holborn Hill. 


```css interactive-example
#example-element {
  width: 100%;
  text-align: left;
}

语法

/* 关键字值 */
column-count: auto;

/* <integer> 值 */
column-count: 3;

/* 全局值 */
column-count: inherit;
column-count: initial;
column-count: revert;
column-count: revert-layer;
column-count: unset;

取值

  • auto
    • : 用来表示列的数量由其他 CSS 属性指定，例如 {{cssxref("column-width")}}。
  • {{cssxref("<integer>")}}
    • : 是个严格的正整型 {{cssxref("<integer>")}}，用来描述元素内容被划分的理想列数。假如 {{cssxref("column-width")}} 也被设置为非零值，此参数仅表示所允许的最大列数。
