CSS Padding in Outlook 2007 and 2010

For those of you who design and develop HTML emails for Outlook 2007 and 2010, you already know that you are bound by tables and you have very limited CSS support. What you might not realize is that these two email clients convert your code from something legible into a seemingly foreign Microsoft language.

One of the more critical conversions that you should be aware of is that Outlook 2007 and 2010 will often move your CSS from div's and headings into nested paragraph and spans. Sometimes, it keeps the outer container, other times it eliminates it entirely.

For example this:

<h2 style="font-size: 15px; font-weight: bold; margin: 0; padding: 17px 0 0 0;">
NEW FASHIONS
</h2>

<div style="font-size: 15px; font-weight: bold; margin: 0; padding: 17px 0 0 0;">
NEW FASHIONS
</div>

<p style="font-size: 15px; font-weight: bold; margin: 0; padding: 17px 0 0 0;">
NEW FASHIONS
</p>

Will get converted to:

p
{mso-style-noshow:yes;
mso-style-priority:99;
mso-margin-top-alt:auto;
margin-right:0in;
mso-margin-bottom-alt:auto;
margin-left:0in;
mso-pagination:widow-orphan;
font-size:12.0pt;
font-family:"Times New Roman","serif";
mso-fareast-font-family:"Times New Roman";
mso-fareast-theme-font:minor-fareast;}
</style>

<h2 style='margin:0in;margin-bottom:.0001pt'>
   <span style='font-size:11.5pt; mso-fareast-font-family:"Times New Roman"'>
   NEW FASHIONS
   <o:p></o:p>
</span>
</h2>

<div>
   <p class=MsoNormal>
     <b>
     <span style='font-size:11.5pt;mso-fareast-font-family:"Times New Roman"'>
       NEW FASHIONS
       <o:p></o:p>
     </span>
   </b>
   </p>
</div>

<p style='margin:0in;margin-bottom:.0001pt'>
   <b>
     <span style='font-size:11.5pt'>
       NEW FASHIONS
       <o:p></o:p>
     </span>
   </b>
</p>

The Problem

As you can see, this conversion moved our CSS from its original box element container to an inline SPAN element and the padding was ignored.

Solutions

One work-around is to avoid padding in block element containers and use margins instead.

<h2 style="font-size: 15px; font-weight: bold; margin-left: 5px; margin-right: 5px; margin-bottom: 5px;">
NEW FASHIONS
</h2>

Note: I did not include the "margin" nor "margin-top" properties in this example because they are not supported by Hotmail.

After extensive testing, we have confirmed that the padding property is supported in TD's. So another fix is to move your padding into the containing TD, for example:

<td style="padding: 17px 0 0 0">
<h2 style="font-size: 15px; font-weight: bold; margin: 0">NEW FASHIONS</h2>
</td>

Thanks for your post. I was trying to figure out why certain HTML element padding properties are being ignored exclusively on 2007 and 2010.

I ended up returning back to my simple full table formatting for padding, instead of defining padding for a particular td, I define a containing table and empty cells with spacer images for exact pixels padding effect. But this information did allow me to take my email templates to a more updated approach. and I will be quoting this post in my blog.
