rails 发邮件模板

rails发邮件模板不允许写css， 只能把css样式用style属性嵌套在html标签中

实例register_complete.html.erb中（邮件html.erb模板）:

<div class="text-center main-body" style="color: #4B5259; background-image: url('http://bnbtrip.oss-cn-hangzhou.aliyuncs.com/assets/images/web/2016/02/bg2.jpg'); padding-bottom: 20px; background-repeat: no-repeat; background-size: cover; font-size: 14px;">

  <h1 class="bnb-text-shadow" style="padding-top: 36px;color: #fff;">

    <%= I18n.t("email.users.register_complete.subject") %>

  </h1>

  <h1 class="bnb-text-shadow">

    <%= I18n.t("email.users.register_complete.subtitle") %>

  </h1>

  <div class="white-bg">

    <div class="content-wrapper">

      <h2 style="margin-bottom: 10px"><%= I18n.t "email.users.register_complete.hi", name: @user.full_name %></h2>

      <h3 style="margin-top: 0;"><%= I18n.t "email.users.register_complete.one" %></h3>

      <p>

        <%= raw I18n.t("email.users.register_complete.p_one") %>

      </p>

      <p>

        <%= raw I18n.t("email.users.register_complete.p_two") %>

      </p>

    </div>

  </div>

</div>
