min-inline-size

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2021.

CSS 属性 min-inline-size 根据元素的书写模式定义了元素区块的横向或纵向最小尺寸。根据 writing-mode 的值，此属性对应于 min-width 或 min-height 属性。

尝试一下

语法

css

/* <length> 值 */
min-inline-size: 100px;
min-inline-size: 5em;

/* <percentage> 值 */
min-inline-size: 10%;

/* 关键词值 */
min-inline-size: max-content;
min-inline-size: min-content;
min-inline-size: fit-content(20em);

/* 全局值 */
min-inline-size: inherit;
min-inline-size: initial;
min-inline-size: revert;
min-inline-size: revert-layer;
min-inline-size: unset;

若为纵向书写模式，则 min-inline-size 的值对应于元素的最小高度；否则对应于元素的最小宽度。与此相关的属性为 min-block-size，此属性定义了元素另一方向的尺度。

取值

min-inline-size 属性的取值与 min-width 和 min-height 属性相同。

形式定义

初始值	`0`

Percentages	inline-size of containing block
计算值	same as `min-width` and `min-height`
动画类型	a length, percentage or calc();

形式语法

min-inline-size = 
  <'min-width'>  

<min-width> = 
  auto                                      |
  <length-percentage [0,∞]>                 |

  max-content                               |
  fit-content( <length-percentage [0,∞]> )  |
  <calc-size()>                             |
  <anchor-size()>                           

<length-percentage> = 
  <length>      |
  <percentage>  

<calc-size()> = 
  calc-size( <calc-size-basis> , <calc-sum> )  

<anchor-size()> = 
  anchor-size( [ <anchor-name> || <anchor-size> ]? , <length-percentage>? )  

<calc-size-basis> = 
  <intrinsic-size-keyword>  |
  <calc-size()>             |
  any                       |
  <calc-sum>                

<calc-sum> = 
  <calc-product> [ [ '+' | '-' ] <calc-product> ]*  

<anchor-name> = 
  <dashed-ident>  

<anchor-size> = 
  width        |
  height       |
  block        |
  inline       |
  self-block   |
  self-inline  

<calc-product> = 
  <calc-value> [ [ '*' | '/' ] <calc-value> ]*  

<calc-value> = 
  <number>        |
  <dimension>     |
  <percentage>    |
  <calc-keyword>  |
  ( <calc-sum> )  

<calc-keyword> = 
  e          |
  pi         |
  infinity   |
  -infinity  |
  NaN
