代理伺服器分類詳解

你还在为居中而烦恼吗，水平居中多个元素、创建响应式布局、垂直和水平同时居中内容。它，display: flex 和 justify-content: center 都可以完成！

display: flex：将元素定义为flex容器
justify-content：定义项目在主轴上的对齐方式

例1：导航菜单居中

<!DOCTYPE html>
<html lang="zh">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
    nav ul {
        display: flex;
        justify-content: center;
        list-style-type: none;
        padding: 0;
    }
    nav li {
        font-size: 16px;
        margin: 0 10px;
    }
    </style>
</head>
<body>
    <nav>
        <ul>
          <li><a href="#">首页</a></li>
          <li><a href="#">关于</a></li>
          <li><a href="#">联系</a></li>
        </ul>
    </nav>
</body>
</html>

例2：图片和文字并排居中

<!DOCTYPE html>
<html lang="zh">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
    .container {
        display: flex;
        justify-content: center;
        align-items: center;
    }
    .container img {
        margin-right: 10px;
        width: 30px;
        height: 30px;
    }
    </style>
</head>
<body>
    <div class="container">
        <img src="../../Web/static/img/LA.png" alt="Logo">
        <h1>公司名称</h1>
    </div>
</body>
</html>

例3：多个块级元素居中

<!DOCTYPE html>
<html lang="zh">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
    .features {
        display: flex;
        justify-content: center;
        flex-wrap: wrap;
    }
    .feature {
        margin: 10px;
        padding: 20px;
        background-color: #f0f0f0;
    }
    </style>
</head>
<body>
    <div class="features">
        <div class="feature">功能1</div>
        <div class="feature">功能2</div>
        <div class="feature">功能3</div>
    </div>
</body>
</html>
