css justify-content属性怎么用?
justify-content 用于设置或检索弹性盒子元素在主轴(横轴)方向上的对齐方式。可以使用 align-content 属性对齐交叉轴上的各项(垂直)。
语法:
justify-content: flex-start|flex-end|center|space-between|space-around|initial|inherit;
属性值:
● flex-start:默认值。项目位于容器的开头。

● flex-end:项目位于容器的结尾。

● center:项目位于容器的中心。

● space-between:项目位于各行之间留有空白的容器内,即均匀分布在线上; 第一项是在起始行,最后一项是在结束行。

● space-around:项目位于各行之前、之间、之后都留有空白的容器内。

● initial:设置该属性为它的默认值。
● inherit:从父元素继承该属性。
