For years developers have been building email in the same way, a 2 table structure where the outer table is set to 100% width and the inner table is set to something like 600px wide resulting in a 600px centered container for your content.
More recently people have been using the spongy/hybrid approach that sets the inner table width a max width of 600px and a width of 100%, so the content will fit the viewport when viewed under 600px. With this method there is also the need for a ‘ghost table’ hidden from everything but Outlook and set to a fixed width of 600px as Outlook doesn’t recognise the max-width property.
More recently I’ve been replacing this inner table with a div as it uses a little less code, but now...
My new approach uses just one table. The width is set to 100% and it contains 3 table cells, the center cell has a width of 600px and the other 2 are left blank so they will automatically fill the remaining space and center the content. It's the same concept as setting
margin:0 auto; often used on the web.
If the viewport is less than 600px the width of the table overrides that of the table cell so it will adjust to fit, therefor giving the same result as the
This new technique uses less code and also gives you a couple more design options.
You can now control the background of the left and right side of the email separately, to give this cool flag effect.
You could maybe use background images instead of colours to recreate the classic Smith and Jones head to heads (British comedians from the 80's).
You can even add additional empty table cells to offset the content, these will automatically align as the viewport gets smaller.
So here is the basic code I use.
<table width="100%" border="0" cellspacing="0" cellpadding="0" bgcolor="#333333" role="presentation" style="table-layout:fixed"> <tr> <td style="font-size:0px"> </td> <td align="center" width="600" bgcolor="white"> <h1> New Table Structure </h1> </td> <td style="font-size:0px"> </td> </tr> </table>
And you can view the code for all the examples here
The left and right table cells both contain
as if they are empty they it can break in some clients. This however has the side effect of creating a one character space either side of the content on mobile. This may well be an effect you like but if not simple add
style="font-size:0px" to remove it.
As an extra plus this new technique also fixes things like the Yahoo! left align bug.
It's still early days and although I've tested this in a few campaigns already, there may still be some limitations I've not yet come across.
N.B I'm already working on a new structure that uses no tables at all. Just need a little more testing on that one first.
