Alignment issue with HTML email in Outlook

Question

I'm having trouble rendering my HTML email correctly in Outlook. The top picture is how it is supposed to look like in Gmail. The second picture is being rendered incorrectly by Outlook 2016. I've been stuck on this issue for the past 2 days. Any helps is greatly appreciate it.

This is the code that is being rendered in HTML:

Answer 1

You've got "740px" for each of the Outlook-specific (if mso) table columns. You would need to make them 33%, 50% and 16% -- but as pixels -- for Outlook to work.

Incidentally, you should also inline the widths for other email environments that don't support <style> blocks. For example, Gmail IMAP doesn't support this. So just put the width:33% inline instead of as a class.

Here's the new code:

    <!-- COLUMN TITLE -->
<!--[if mso | IE]></td></tr></table><table align="center" border="0" cellpadding="0" cellspacing="0" class="" style="width:740px;" width="740" bgcolor="#ffffff" ><tr><td style="line-height:0px;font-size:0px;mso-line-height-rule:exactly;"><![endif]-->
