I use very simple inline styling like so:
<html>
<head></head>
<body text="#000000" bgcolor="#FFFFFF">some text<br>
<span style="font-family: Tahoma,Verdana,Geneva,sans-serif; font-size: 10pt; color:#333333;">
some other text
</span>
</body>
</html>
However, the Text "some other text" doesn't display any different from the text "some text" in gmail (and in Outlook.com)-- although the inline styles ARE still there in the gmail page source code. It doesn't matter if I use px or pt or no unit at all.
So what is wrong here, and how can I get other text size and color in gmail?
