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>

在这种情况下,我试图在button::before和button::after中垂直对齐文本内容,我能够使用vertical-align: text-top让它工作。

button::after {
  vertical-align: text-top;
}

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 >

.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>

第一个子将在中心垂直和水平对齐

网格css方法

#包装{ 位置:绝对的; 上图:0; 底部:0; 右:0; 左:0; 显示:网格; Grid-template-columns: repeat(3,1fr); Grid-template-rows: repeat(3,1fr); } .main { background - color: # 444; } < div id = "包装" > < div class = "盒子" > < / div > < div class = "盒子" > < / div > < div class = "盒子" > < / div > < div class = "盒子" > < / div > <div class="box main"></div> < / div >

方法6

/*Change units to "%", "px" or whatever*/ #wrapper{ width: 50%; height: 70vh; background: rgba(0,0,0,.5); position: absolute; top: 0; right: 0; bottom: 0; left: 0; margin: auto; } #left{ width: 50%; height: 50vh; position: absolute; top: 0; bottom: 0; left: 0; margin: auto; background: red; } #right{ width: 50%; height: 50vh; position: absolute; top: 0; bottom: 0; right: 0; margin: auto; background: green; } .txt{ text-align: center; line-height: 50vh; } <div id="wrapper"> <div id="left" class="txt">Left</div> <div id="right" class="txt">Right</div> </div>

    .container{ 
               width: 50%;  //Your container width here
               height: 50%; //Your container height here
               position: absolute; 
               top: 0; 
               right: 0;  
               bottom: 0; 
               left: 0; 
               margin: auto;
    }

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>
