Is there an equivalent of CSS max-width that works in HTML emails?

I'm trying to create an HTML email that will display properly in all widely used email clients. I'm wrapping the whole email in a table, and I'd like it to have a width that is up to 98% of the available width, but no greater than 800 pixels. Like this: <table style="width:98%; max-width:800px;">

But I'm not doing it that way, since according to this Outlook 2007 does not support the CSS width property.

Instead, I'm doing this: <table width="98%">

Is there any way to also set a max-width without relying on CSS?

Solution 1:

Yes, there is a way to emulate max-width using a table, thus giving you both responsive and Outlook-friendly layout. What's more, this solution doesn't require conditional comments.

Suppose you want the equivalent of a centered div with max-width of 350px. You create a table, set the width to 100%. The table has three cells in a row. Set the width of the center TD to 350 (using the HTML width attribute, not CSS), and there you go.

If you want your content aligned left instead of centered, just leave out the first empty cell.

Example:

<table border="0" cellspacing="0" width="100%">
    <tr>
        <td></td>
        <td width="350">The width of this cell should be a maximum of 
                  350 pixels, but shrink to widths less than 350 pixels.
        </td>
        <td></td>
     </tr>
</table> 

In the jsfiddle I give the table a border so you can see what's going on, but obviously you wouldn't want one in real life:

Solution 2:

There is a trick you can do for Outlook 2007 using conditional html comments.
The code below will make sure that Outlook table is 800px wide, its not max-width but it works better than letting the table span across the entire window.

<!--[if gte mso 9]>
<style>
#tableForOutlook {
  width:800px;
}
</style>
<![endif]-->

<table style="width:98%;max-width:800px">
<!--[if gte mso 9]>
  <table id="tableForOutlook"><tr><td>
<![endif]-->
    <tr><td>
    [Your Content Goes Here]
    </td></tr>
<!--[if gte mso 9]>
  </td></tr></table>
<![endif]-->
<table>
