文字

语法：

outline-offset：<length>

默认值：0

适用于：所有元素

继承性：无

动画性：当取值为<length>时

计算值：绝对长度

取值：

<length>：用长度值来定义轮廓偏移。允许负值。

说明：

设置或检索对象外的线条轮廓偏移容器的值。参阅 <' outline '> 属性。

outlines相关属性不占据布局空间，不会影响元素的尺寸；
outlines可能是非矩形；
outline-offset是以border边界作为参考点的，从0开始，正值从border边界往外延，负值从border边界往里缩。
对应的脚本特性为outlineOffset。

兼容性：

Values	IE	Firefox	Chrome	Safari	Opera	iOS Safari	Android Browser	Android Chrome
