Recently I’ve made some minor adjustments on newsletter bound HTML documents. One particular document was made in the iContact WYSIWYG editor and as you can expect the HTML markup was horrendous. Even worse than the markup was the various ways the email displayed in different email viewing environments. Hotmail, Outlook, and Gmail all displayed this same email differently.

The main issue I was experiencing was a mysterious 3px bottom ‘padding’ given to all img elements wrapped in an anchor tag and lined up horizontally using tds (apparently tables are still the norm for email marketing). No actual CSS padding or margin was being applied to the img or any of its container elements. I’m still not entirely sure what was causing the 3px ‘padding’ but adding style=”display:block” to each img element fixed the problem.
