CSS |基于弹性的属性

原文:https://www.geeksforgeeks.org/css-flex-basis-property/

CSS 中的 flex-based 属性用于指定灵活项的初始大小。如果元素不是柔性项,则不使用 flex 属性。

语法:

flex-basis: number|auto|initial|inherit;

默认值:

  • 自动

房产价值:

  • 数字:是定义该项目初始长度的长度单位。
  • 自动:为默认值,如果没有指定长度,长度将根据其内容而定。
  • 初始值:将属性设置为默认值。
  • inherit: 它指定属性应该从其父元素继承其值。
