大家好，我是讯享网，很高兴认识大家。

1、我们可以利用"margin:0 auto"来设置元素水平居中。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
        .center{
            margin:0 auto;
            width:100px;
            height:100px;
            background-color: aqua;
        }
    </style>
</head>
<body>
    <div class="center"></div>
</body>
</html>

            background-color: aqua;
        }
    </style>
</head>
<body>
    <div class="center">我想要居中</div>

    <style>
        .container {
            width: 300px;
            height: 300px;
            background-color: aqua;
            display: flex;
            justify-content: center;
            align-items: center;
        }
    </style>

    <div class="container">
