如何横向和横向div 垂直居中

发布于 2024-10-05 05:47:37 字数 320 浏览 1 评论 0原文

这是源代码：

<div id = "outer">
     <div id="top">
     ....
     </div>

     <div id="inner">
     ....
     </div>

     <div id="bottom">
     ....
     </div>
</div>

如何我如何制作div（id内部），水平和垂直？垂直中心？

我可以水平居中，但不能垂直居中......

原文

Here is the source code:

<div id = "outer">
     <div id="top">
     ....
     </div>

     <div id="inner">
     ....
     </div>

     <div id="bottom">
     ....
     </div>
</div>

How do I make the div (id inner), horizontal & vertical center?

I can horizontal center, but I can't make a vertical center...

如果您知道内部 div 的尺寸，则可以使用 CSS。

#outer {
    position: relative;
}

#inner {
    position: absolute;
    width: 200px;
    height: 200px;
    left: 50%;
    top: 50%;
    margin-top: -100px;
    margin-left: -100px;
}

还有其他选项使用 display: table-cell 和 vertical-align: middle 等。

其他选项包括 JavaScript 来动态确定内部 div 的尺寸并设置负数边距就像之前的答案一样。

If you know the dimensions of the inner div you can use CSS.

#outer {
    position: relative;
}

#inner {
    position: absolute;
    width: 200px;
    height: 200px;
    left: 50%;
    top: 50%;
    margin-top: -100px;
    margin-left: -100px;
}

There are other options using display: table-cell and vertical-align: middle, etc.

Other options include JavaScript to dynamically determine the dimensions of the inner div and set the negative margins like the previous answers.

使用 JavaScript 或尝试使用 CSS 中的垂直居中 。

我猜你想要一个 div 来对齐垂直和水平中心，并在所有浏览器中具有动态高度和宽度。

jSfiddle

HTML

<div class="main">
    <div class="contentWrapper">
        <div class="content">My Content </br> Goes here</div>
    </div>           
</div>

CSS

.main {
    border: 1px solid #f00;
    height: 400px;
    width: 400px;
    position: relative
}
.contentWrapper {
    display: table;
    width: 100%;
    height: 100%;
    *height: auto;
    *position: absolute;
    *top: 50%;
}
.content {
    display: table-cell;
    text-align: center;
    vertical-align: middle;
    *position: relative;
    *top: -50%;
}

I guess you want a div to align vertical and horizontal center have dynamic height and width in all browsers.

HTML

<div class="main">
    <div class="contentWrapper">
        <div class="content">My Content </br> Goes here</div>
    </div>           
</div>

CSS

.main {
    border: 1px solid #f00;
    height: 400px;
    width: 400px;
    position: relative
}
.contentWrapper {
    display: table;
    width: 100%;
    height: 100%;
    *height: auto;
    *position: absolute;
    *top: 50%;
}
.content {
    display: table-cell;
    text-align: center;
    vertical-align: middle;
    *position: relative;
    *top: -50%;
}

您必须使用 display: table-cell;, vertical-align: middle; 来完成此操作，无需使用 JavaScript。
