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?

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.

<!DOCTYPE html>
<html>
    <head>

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

调整线高度以获得垂直对齐。

line-height: 90px;

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>

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