邮件模板定义

在发送通知邮件的时候，假如可以有漂亮的邮件模板就更好了，但是出于安全的原因，邮件一般不支持 link 或者 style 样式，只能通过内联的方式。找到了 The Automatic CSS Inliner Tool。有了自动转换工具，那就简单了。首先，编写普通的 html 代码，把 css 样式放到 style 标签中

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8" />
    <title>邮件模板</title>
    <style>
        .panel {
            width: 300px;
            margin: 20px;
            border-radius: 4px;
            border: 1px solid #bce8f1;
        }
        .panel-title {
            padding: 10px 15px;
            color: #31708f;
            background-color: #d9edf7;
            border-color: #bce8f1;
            border-radius: 4px 4px 0 0;
        }
        .panel-body {
            padding: 15px;
            color: #3a87ad;
            font-size: 30px;
            text-align: center;
        }
        .panel-success {
            border: 1px solid #d6e9c6;
        }
        .panel-success .panel-title {
            color: #3c763d;

            border-color: #d6e9c6;
        }
        .panel-success .panel-body {
