创建响应式HTML电子邮件模板时,关键是确保模板在所有电子邮件客户端中都能正常显示,尤其是在手机和平板上。以下是一个简单的HTML电子邮件模板示例,它使用了响应式设计技术:
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Responsive Email Template</title>
    <style type="text/css">
        body { margin: 0; padding: 0; }
        table { border-collapse: collapse; }
        .header { font-family: Arial, sans-serif; font-size: 18px; font-weight: bold; }
        .content { width: 100%; }
        .column { display: inline-block; vertical-align: top; }
        .left { width: 30%; background-color: #e5e5e5; text-align: center; }
        .right { width: 70%; text-align: center; }
        @media only screen and (max-width: 600px) {
            .content { width: 100%; }
            .column { display: block; }
            .left, .right { width: 100%; text-align: center; }
        }
    </style>
</head>
<body>
    <table class="header" width="100%" cellpadding="0" cellspacing="0" role="presentation">
        <tr>
            <th>Header Content</th>
        </tr>
    </table>
    <table class="content" width="100%" cellpadding="0" cellspacing="0" role="presentation">
        <tr>
            <td class="column left">
                <img src="https://example.com/image.png" alt="Image" width="200" />
            </td>
            <td class="column right">
                <h1>Main Content Heading</h1>
                <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit...</p>
                <!-- Call to action button -->
                <table role="presentation" cellspacing="0" cellpadding="0">
                    <tr>
                        <td style="border-radius: 4px; background-color: #3498db; text-align: center;" width="200" align="center" valign="middle">
                            <a href="https://example.com" target="_blank" style="text-decoration: none; color: #ffffff; display: block; padding: 10px 25px;">Button Text</a>
                        </td>
                    </tr>
                </table>
            </td>
        </tr>
    </table>
    <table class="footer" width="100%" cellpadding="0" cellspacing="0" role="presentation">
        <tr>
            <td>Footer Content</td>
        </tr>
    </table>
</body>
</html>这个模板包括了响应式设计的基本原则,例如使用百分比宽度和 \`display: inline-bloc
