Miscellaneous Level 2

最大高度 | max-height

max-height CSS属性设置元素的最大高度。它可以防止height属性的使用值变得大于指定的值max-height

/* <length> value */
max-height: 3.5em;

/* <percentage> value */
max-height: 75%;

/* Keyword values */
max-height: none;
max-height: max-content;
max-height: min-content;
max-height: fit-content;
max-height: fill-available;

/* Global values */
max-height: inherit;
max-height: initial;
max-height: unset;

max-height覆盖height,但min-height覆盖max-height

Initial value

none

应用对象

all elements but non-replaced inline elements, table columns, and column groups

是否可继承

no

百分比值

The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the percentage value is treated as none.

媒体

visual

计算值

the percentage as specified or the absolute length or none

动画类型

a length, percentage or calc();

规范顺序

the unique non-ambiguous order defined by the formal grammar

语法

<length>最大高度,表示为 <length><percentage>最大高度,以<percentage>包含块的高度表示。如果未明确指定包含块的高度,则将百分比值视为零。

关键字值

none高度没有最大值。

max-content内在的首选高度。

min-content内在的最小高度。

fill-available包含块的高度减去垂直边距,边框和填充。(请注意,某些浏览器这个关键字实现一个古老的名字,available。)

fit-content同为max-content.

形式语法

<length> | <percentage> | none | max-content | min-content | fit-content | fill-available

实例

table { max-height: 75%; }

form { max-height: none; }

CSS

层叠样式表( Cascading Style Sheets )是一种用来表现 HTML 或 XML 等文件样式的计算机语言。CSS 不仅可以静态地修饰网页,还可以配合各种脚本语言动态地对网页各元素进行格式化。
