语法:

flex-basis:<length> | <percentage> | auto | content

默认值auto

适用于:flex子项

继承性:无

动画性:是,当值为非关键字时

计算值:指定值

取值:

  • <length>:用长度值来定义宽度。不允许负值

  • <percentage>:用百分比来定义宽度。不允许负值

  • auto:无特定宽度值,取决于其它属性值

  • content:基于内容自动计算宽度

说明:

设置或检索弹性盒伸缩基准值。
  • 如果所有子元素的基准值之和大于剩余空间,则会根据每项设置的基准值,按比率伸缩剩余空间

  • 对应的脚本特性为flexBasis
