max-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 max-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大尺寸。根据 writing-mode 的值，此属性对应于 max-width 或 max-height 属性。

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