为 Gmail 设计 HTML 电子邮件样式

我正在生成一个使用内部样式表的 html 电子邮件，即。

<!doctype html>
<html>
<head>
<style type="text/css">
h2.foo {color: red}
</style>
</head>
<body>
<h2 class="foo">Email content here</foo>
</body>
</html>

在 Gmail 中查看时，内部样式表中的所有样式似乎都被忽略了。Gmail 似乎忽略了除内联规则以外的所有样式，例如。

 <h2 style="color: red">Email content here</foo>

这是我用 Gmail 浏览 HTML 电子邮件时唯一的样式选择吗？

Use inline styles for everything. This site will convert your classes to inline styles: http://premailer.dialect.ca/

Gmail started basic support for style tags in the head area. Found nothing official yet but you can easily try it yourself.
It seems to ignore class and id selectors but basic element selectors work.

<!doctype html>
<html>
<head>
<style type="text/css">
p{font-family:Tahoma,sans-serif;font-size:12px;margin:0}
</style>
</head>
<body>
<p>Email content here</p>
</body>
</html>

it will create a style tag in its own head area limited to the div containing the mail body

<style>div.m14623dcb877eef15 p{font-family:Tahoma,sans-serif;font-size:12px;margin:0}</style>

As others have said, some email programs will not read the css styles. If you already have a web email written up you can use the following tool from zurb to inline all of your styles:

This comes in extremely handy when using templates like those mentioned above from mailchimp, campaign monitor, etc. as they, as you have found, will not work in some email programs. This tool leaves your style section for the mail programs that will read it and puts all the styles inline to get more universal readability in the format that you wanted.

Note that services and tools for sending emails may be able to inline your CSS for you, allowing CSS in <style> tags to work in Gmail.

For instance, if you're sending emails with MailChimp, your CSS from <style> tags will get inlined automatically by default. With Mandrill, you can enable this functionality (although it's disabled by default for performance reasons) by checking the "Inline CSS Styles in HTML Emails" box in the "Sending Defaults" section of the Settings tab:

The answers here are outdated, as of today Sep 30 2016. Gmail is currently rolling out support for the style tag in the head, as well as media queries. If Gmail is your only concern, you're safe to use classes like a modern developer!

For reference, you can check the official gmail CSS docs.

As a side note, Gmail was the only major client that didn't support style (reference, until they update anyway). That means you can almost safely stop putting styles inline. Some of the more obscure clients may still need them.

I agree with everyone who supports classes AND inline styles. You might have learned this by now, but if there is a single mistake in your style sheet, Gmail will disregard it.

You might think that your CSS is perfect, because you've done it so often, why would I have mistakes in my CSS? Run it through the CSS Validator (for example http://www.css-validator.org/) and see what happens. I did that after encountering some Gmail display issues, and to my surprise, several Microsoft Outlook specific style declarations showed up as mistakes.

Which made sense to me, so I removed them from the style sheet and put them into a only for Microsoft code block, like so:

<!--[if mso]>
<style type="text/css">
body, table, td, .mobile-text {
font-family: Arial, sans-serif !important;
}
</style>
<xml>
<o:OfficeDocumentSettings>
<o:AllowPNG/>
<o:PixelsPerInch>96</o:PixelsPerInch>
</o:OfficeDocumentSettings>
</xml>
<![endif]-->

This is just a simple example, but, who know, it might come in handy some time.

I had the same problem while designing a template in Mailjet. Solution of the problem was minified CSS code inside <style> tags.

@shawn did give an example how to use a combination of styling in the head section together with inline styling. Some email clients (Outlook, Gmail, etc.) have tricky things, these can be fixed with css in the head style.

The extra table <table width="580"> is for Outlook to solve 'width' problems and also to center the layout.
