我有一个div设置显示:块(90px高和宽),我有一些文本在里面。

我需要文本在中心垂直和水平对齐。

我已经尝试了text-align:center,但它不做垂直居中部分,所以我尝试了vertical-align:middle,但它不起作用。

什么好主意吗?

试试下面的例子。我为每个类别添加了示例:水平和垂直

<!DOCTYPE html>
<html>
    <head>
        <style>
            #horizontal
            {
                text-align: center;
            }
            #vertical
            {
                position: absolute;
                top: 50%;
                left: 50%;
                transform: translateX(-50%) translateY(-50%);
            }
         </style>
    </head>
    <body>
         <div id ="horizontal">Center horizontal text</div>
         <div id ="vertical">Center vertical text</div>
    </body>
</html>

您可以尝试以下方法:

If you have a single word or one line sentence, then the following code can do the trick. Have a text inside a div tag and give it an id. Define the following properties for that id. id-name { height: 90px; line-height: 90px; text-align: center; border: 2px dashed red; } Note: Make sure the line-height property is same as the height of the division. Image But, if the content is more than one single word or a line then this doesn’t work. Also, there will be times when you cannot specify the size of a division in px or % (when the division is really small and you want the content to be exactly in the middle). To solve this issue, we can try the following combination of properties. id-name { display: flex; justify-content: center; align-items: center; border: 2px dashed red; } Image These 3 lines of code sets the content exactly in the middle of a division (irrespective of the size of the display). The "align-items: center" helps in vertical centering while "justify-content: center" will make it horizontally centered. Note: Flex does not work in all browsers. Make sure you add appropriate vendor prefixes for additional browser support.

这是非常简单的代码,为我工作!它只有一行,你的文本将水平居中。

.center-horizontally{
  justify-content: center;
}
<Card.Footer className="card-body-padding center-horizontally">
  <label className="support-expand-text-light">Call or email Customer Support to change</label>
</Card.Footer>

输出如下所示:

在父div中添加以下代码

display: grid;
place-items: center;

对我来说,这是最好的解决方案:

HTML:

<div id="outer">
    <img src="logo.png">
</div>

CSS:

#outer {
  position: fixed;
  top: 50%;
  left: 50%;
  /* Bring your own prefixes */
  transform: translate(-50%, -50%);
}

Use:

# Parent
{
  display: table;
}

# Child
{
  display: table-cell;
  width: 100%; /* As large as its parent to center the text horizontally */
  text-align: center;
  vertical-align: middle; /* Vertically align this element on its parent */
}
