文字
语法：
order：<integer>
默认值：0
适用于：flex子项和flex容器中的绝对定位子元素
继承性：无
动画性：是
计算值：指定值
取值：
<integer>：用整数值来定义排列顺序，数值小的排在前面。可以为负值。
说明：
设置或检索弹性盒模型对象的子元素出現的順序。
order定义将会影响 <' position '> 值为
static元素的层叠级别，数值小的会被数值大的盖住。demo：
.test { display: flex; } .item2 { order: -1; margin: -30px; } <div class="test"> <p class="item1">flex item1</p> <p class="item2">flex item2</p> </div>
此时，item1将会盖在item2之上
对应的脚本特性为order。
