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>

我使用这个CSS代码:

display: grid;
justify-content: center;
align-items: center;

.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

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;
    }

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;
}

如果CSS3是一个选项(或者你有一个备用方案),你可以使用transform:

.center {
    right: 50%;
    bottom: 50%;
    transform: translate(50%,50%);
    position: absolute;
}

与上面的第一种方法不同,你不想使用left:50%和负平移,因为在IE9+中有一个溢出的bug。如果使用正的右值,就不会看到水平滚动条。

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 >
