Styles not working in Gmail

问题

I'm working on sending emails to various email clients(such as yahoo,hotmail,gmail,....).

I have a div with id OrderInfo inside that I have a variable which generates a dynamic table.

HTML

<div id="OrderInfo">
  variable 
</div>

The dynamic table generates headers(th) with lower case, so I want to change that to uppercase and few more styling. So I have written a selectors

CSS

#OrderInfo table tr th {
  text-transform: uppercase;
  background-color: #737373;
  color: white;
}

This is working fine for yahoo, hotmail but not for gmail.

I came across that only inline styles work for gmail but how can I the styles of modify a dynamic one.

I have no control on the variable (I mentioned in the div) it generates a table with values which processes while sending to the client.

So I cannot keep a static table and cannot change the way it renders

回答1:

gmail as well as some other web and desktop/mobile clients strips away css stylesheets either imported or embedded in a <style>...</style> node in the head

Put them inline:

<div id="OrderInfo">
    <table>
        <tr>
            <td style="text-transform: uppercase; background-color: #737373; color: white;">
                <!-- .......... -->
            </td>
        </tr>
    </table>
</div>

As a more general advice: building email html is not trivial as final result may vary a lot depending on the recipent's mail client.

The general rule is to make the html as simple as possible, avoiding "modern" css features; use nested tables instead of divs when possible (some says build the html as if you were building a 15 years ago webpage).

The above is very general and may not be always true.

There are several resources online that gives advices and rules on how to make an html email or template.

Finally the only and one rule to always follow if you want to be sure of the result: test your messages with various client

UPDATE 2018

GMAIL now and from a while ago has been supporting embedded CSS, so you can use CSS inside tag <style> in head, it even allow/supports the use of media queries.

Many email service provide not support to css included in email template. Instead use inline css.

Also, Email template should be formed using tables as it only support HTML3. You can use HTML4/5 elements withing td tags

Do check this link. It will help you to build email template.

Try with this styling making your link red with no special effect for the hover situation:

a:link{color: red}
a:visited{color: red}
a:hover{color: red}
a:active{color: red}

This works fine for me, but if anyone of the 4 statements are missing it will not work neither in a gmail client nor in Outlook. They must also appear in the order shown above.
