Question

我正在发送来自Django的HTML电子邮件：

template_html = "email/deposit_email.html"
                email_context = Context({ 'contact': contact, 'amount': amount})

                subject, from_email, to = 'Deposit Successfully created.', settings.EMAIL_HOST_USER, contact_email
                text_content = "Thank you for depositing the amount of " + str(amount) + "."

                html = loader.get_template(template_html)
                html_content = html.render(email_context)
                msg = EmailMultiAlternatives(subject, text_content, from_email, [to])
                msg.attach_alternative(html_content, "text/html")
                msg.send()

我收到的电子邮件没有任何CSS。我使用：

在Django中加载模板本身

return render(request, 'templatename_html')

模板正在加载django中的所有css，但不是在gmail中发送电子邮件时。怎么了？

Answer 1

正如其他开发人员提到的，电子邮件客户端不会加载外部css，因此您必须内联它。手动内联css是一个糟糕的决定。内联css有库。其中一个是django-inlinecss。您可以完全按照原样保留代码。您需要做的就是安装django-inlinecss并更改“deposit_email.html”。我不知道它看起来如何，因为你没有发布它，所以我给你一个简单的标题的例子，就像我之前用过的成功的电子邮件模板。

{% load inlinecss %}
{% inlinecss "css/email.css" %}

{% endinlinecss %}

这里没什么了。第一行加载inlinecss标记。

{% load inlinecss %}

第二行启动html，这将是css内联。它还加载email.css，它可以是你的django项目中的任何静态文件。

{% inlinecss "css/email.css" %}

在基于表格的模板之后，该模板具有带有django块'内容'的标题和正文。最后一行是

{% endinlinecss %}

哪个以inlinecss结束。如您所见，我将内联整个模板。我建议有一个或多个父电子邮件模板，其中包含模板结构，而不是使用特定电子邮件的模板继承。这样你就需要指定模板并将你的css内联一次。

最后但并非最不重要。为了使表格模板能够很好地发挥作用，您需要使用email.css样式。 CSS有点大，但性质简单。添加自己的样式。
