Style boxSizing 属性

❮ Style 对象

实例

改变 boxSizing 属性:

document.getElementById("myDIV").style.boxSizing = "border-box";
亲自试一试 »

定义和用法

boxSizing 属性允许您以特定的方式定义匹配某个区域的特定元素。

例如,如果您需要并排放置两个带边框的框,可通过将 boxSizing 设置为 "border-box" 来实现。这可令浏览器呈现出带有指定宽度和高度的框,并把边框和内边距放入框中。


浏览器支持

属性
boxSizing Yes Yes Yes Yes Yes

语法

返回 boxSizing 属性:

object.style.boxSizing

设置 boxSizing 属性:

object.style.boxSizing = "content-box|border-box|initial|inherit"

属性值

描述
content-box 默认值。这是由 CSS2.1 规定的宽度和高度的行为。设定的宽度和高度(及 min/max 属性)分别应用到元素的内容框的宽度和高度。在设定的宽度和高度之外绘制元素的内边距和边框。
border-box 为元素设定的宽度和高度(及 min/max 属性)决定了元素的边框盒。也就是说,为元素指定的任何内边距和边框都将在已设定的宽度和高度内进行绘制。通过把已设定的 'width' 和 'height' 属性分别减去边框和内边距才能得到内容的宽度和高度。
initial 设置该属性为它的默认值。请参阅 initial
inherit 从父元素继承该属性。请参阅 inherit

技术细节

默认值: content-box
返回值: 字符串,表示元素的 box-sizing 属性。
