Style minHeight 属性
定义和用法
minHeight 属性设置或返回元素的最小高度。
minHeight 属性只在块级元素或绝对/固定位置的元素发挥作用。
语法
设置 minHeight 属性：
Object.style.minHeight="length|%|inherit"
返回 minHeight 属性：
Object.style.minHeight
| 值 | 描述 |
|---|---|
| length | 使用 px、cm 等单位定义最小高度。默认是 0。 |
| % | 定义最小高度为父元素的百分比。 |
| inherit | minHeight 属性的值从父元素继承。 |
浏览器支持
所有主要浏览器都支持 minHeight 属性。
注意：IE7 及更早的版本不支持 "inherit" 值。IE8 只有规定了 !DOCTYPE 才支持 "inherit"。IE9 支持 "inherit"。
