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
