文字
语法：
box-pack：start | center | end | justify
默认值：start
适用于：伸缩盒容器
继承性：无
动画性：否
计算值：指定值
取值：
start：设置伸缩盒对象的子元素从开始位置对齐（大部分情况等同于左对齐，受）
center：设置伸缩盒对象的子元素居中对齐
end：设置伸缩盒对象的子元素从结束位置对齐（大部分情况等同于右对齐）
justify：设置或伸缩盒对象的子元素两端对齐
说明：
设置或检索伸缩盒对象的子元素的对齐方式。查看其兄弟属性box-align，两者的效果正好（相反）互补
效果等同于过渡版本的flex-pack属性和新版本的justify-content属性；
box-pack的对齐方式受box-orient影响；
默认情况下（即box-orient设置为horizontal）start和end所呈现的效果等同于左对齐和右对齐；
当box-orient设置为vertical时，start和end所呈现的效果等同于顶部对齐和底部对齐；
对应的脚本特性为boxPack。
兼容性：
| Values | IE | Firefox | Chrome | Safari | Opera | iOS Safari | Android Browser | Android Chrome |
