我试图垂直居中我的标签内容,但当我添加CSS样式display:inline-flex时,水平文本对齐消失了。

我怎么能使文本对齐x和y为我的每个制表?

* { box-sizing: border-box; } #leftFrame { background-color: green; position: absolute; left: 0; right: 60%; top: 0; bottom: 0; } #leftFrame #tabs { background-color: red; position: absolute; top: 0; left: 0; right: 0; height: 25%; } #leftFrame #tabs div { border: 2px solid black; position: static; float: left; width: 50%; height: 100%; text-align: center; display: inline-flex; align-items: center; } <div id=leftFrame> <div id=tabs> <div>first</div> <div>second</div> </div> </div>

下面是获得理想结果的Flex-box方法

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width"> <title>Flex-box approach</title> <style> .tabs{ display: -webkit-flex; display: flex; width: 500px; height: 250px; background-color: grey; margin: 0 auto; } .f{ width: 200px; height: 200px; margin: 20px; background-color: yellow; margin: 0 auto; display: inline; /*for vertically aligning */ top: 9%; /*for vertically aligning */ position: relative; /*for vertically aligning */ } </style> </head> <body> <div class="tabs"> <div class="f">first</div> <div class="f">second</div> </div> </body> </html>

另一种方法是使用表:

<div style="border:2px solid #8AC007;身高:200 px;宽度:200 px;" > <表风格= "宽度:100%;高度:100%”> < tr风格= "高度:100%”> < td风格= "高度:100%;Text-align:center">你好,这里有多行,这太长了,太棒了,伙计</td> < / tr > 表> < / < / div >

只要让上下左右都为0。

<html>
<head>
<style>
<div> 
{
position: absolute;
margin: auto;
background-color: lightblue;
width: 100px;
height :100px;
padding: 25px;
top :0;
right :0;
bottom:0;
left:0;
}


</style>
</head>
<body>

<div> I am in the middle</div>

</body>
</html>

如果你喜欢它没有flexbox,网格,表格或垂直对齐:中间;

你可以:

HTML

<div class="box">
    <h2 class="box__label">square</h2>
</div>

CSS

.box {
    box-sizing: border-box;
    width: 100px;
    height: 100px;
    text-align: center;
    border: 1px solid black;
}

.box__label {
    box-sizing: border-box;
    display: inline-block;
    transform: translateY(50%);
    text-align: center;
    border: 1px solid black;
}

对我来说,最简单和最干净的解决方案是使用CSS3属性“transform”:

.container { 位置:相对; } .container a { 位置:绝对的; 上图:50%; 变换:翻译(0 -50%); } < div class = "容器" > <a href="#">Hello world!< / > < / div >

.align { display: flex; width: 400px; height: 400px; border: solid 1px black; align-items: center; justify-content: space-around; } .align div:first-child { width: 20px; height: 20px; background-color: red; position: absolute; } .align div { width: 20px; height: 20px; background-color: blue; } <div class='align'> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> </div>
