CSS justify-content 属性

CSS 中的justify-content属性用于描述弹性盒子容器的对齐方式。它包含沿着分布在浏览器中的 flex 容器的主轴的内容项之间和周围的空间。

注意:此属性不能用于沿垂直轴描述项目或容器。为了垂直对齐项目,我们可以使用align-items 属性

在应用了 lengths 和 auto margins 属性后,对齐是可能的,即,如果在Flexbox 布局中至少有一个具有flex-grow 属性而不是 0 的灵活元素,那么它不会影响并且有任何影响不会有任何可用空间。

句法:

justify-content: flex-start|flex-end|center|space-between|
space-around|space-evenly|initial|inherit;

属性值:

flex-start:它是用于从容器开始对齐弹性项目的默认值。

句法:

justify-content: flex-start;

示例:此示例说明justify-content属性,其中属性值设置为flex-start以从容器的开头对齐项目。
