为什么我的div不对齐？（CSS网页设计布局）

时间：2019-10-02 17:35:45

标签： css

div类容器用于包装网页的所有其他项目，我想集中对齐此容器，但似乎无法弄清为什么它不起作用。

编辑：我希望容器本身以视点为中心，然后我想将它们各自对齐到它们自己的容器中。

edit 2：我已经弄清楚了，谢谢大家的回答。我将HTML选择器更改为主体，然后将显示更改为flex，最后将self-self更改为align-items。

* {
margin: 0;
padding: 0;
}

html {
display: block;
flex-direction: column;
width: 100%;
justify-self: center;
}

h1 {
text-align: center;
}

.sub {
position: absolute;
}

.container {
width: 50%;
border: 2px black solid;
box-sizing: border-box;
display: inline-flex;
position: relative;
}

您是否正在寻找类似的东西？

给出container display: flex和justify-content: center;的父元素，然后让flexbox发挥作用。这将使子元素在X轴上居中

* {
margin: 0;
padding: 0;
}

html {
display: block;
flex-direction: column;
width: 100%;
}

body{
width: 100%;
display: flex;
justify-content: center;

color: black;
}

h1 {
text-align: center;
}

.sub {
position: absolute;
}

.container {
width: 50%;
border: 2px black solid;
box-sizing: border-box;
text-align: center;
}

<html>
<body>

<div class="container">
HELLO IM THE CONTAINER
</div>
