css练习-容器内多元素水平居中-flexbox布局应用_html/css_WEB-ITnose

想要实现这样一个父元素中的子元素都是居中的

只需在父元素上加样式

{display: flex;flex-direction: column;align-items:center;}
Copy after login

设置为flexbox布局,方向为纵向排列,第三句是使其居中。

如果三个子元素的距离要自己设定,就设置margin-top或margin-bottom就好了;

如果让其自动调整,可以给父元素的样式再加上

{justify-content:space-around;}
Copy after login

这样剩余的空间会自动分配到各元素周边:)

刚开始觉得没什么必要用sass,现在发现很多css代码还是复用性很高的

为这个案例就算攒了一个小小的传参的mixin了,默认自动调整,也可以传参false,不自动调整

@mixin multi-elements-center($auto:true){display:flex;flex-direction:column;align-items:center;@if $auto{justify-content:space-around;}}
Copy after login

每天进步一点点,加油:)
