If you need to control the mobile padding in your Email Design System, there are a couple of options to achieve this in Taxi.

Option 1

The first can be used if you want a document level field to control mobile padding across multiple modules. In other words, it would be the same across all modules.

In your media query you can include a class, such as: mobile_padding, with a certain value as the default, for example 10px.

<style type="text/css">
@media screen and (max-width: 640px) {
.mobile_padding {
 padding-top: 10px!important;

You can then have a field in document settings, or create a separate formatting module with a field, that will be used to control mobile padding.

<field type="number" name="mob_padding" label="Mobile padding"></field>

Then, you would use a replace attribute in the style tag above in order to reference this field in the media query.

<style type="text/css" replace="@media screen and (max-width: 640px) { 
.mobile_padding { padding-top: {{document.mob_padding}}px!important; }">

And then throughout the HTML you can use this class in the relevant places.

<td class="mobile_padding">

So, whatever number is used in the number field mentioned above, will get used in the style tag/media query. And this will control any HTML that is using that class name.

Option 2

This second option would be used when you want to control the mobile padding separately in different modules.

Instead of having one class and a field to control the value of it, you will need a class for each of the different padding options you want.

<style type="text/css">
@media screen and (max-width: 640px) {
.mobile_padding10 {
 padding-top: 10px!important;
.mobile_padding20 {
 padding-top: 20px!important;
 .mobile_padding30 {
 padding-top: 30px!important;

And then in the module where this is used, you can have a dropdown field with the values matching the values in the media query.

<field type="dropdown" name="mob_padding">
 <choice value="10"></choice>
 <choice value="20"></choice>
 <choice value="30"></choice>

And when you reference this field you need to do so in a replace-class attribute.

<td replace-class="mobile_padding{{mob_padding}}">

Whatever option you select in the dropdown will get used in the replace-class attribute above. For example, if you select 10 from the dropdown the class would become mobile_padding10 and the CSS from this class would get used.

This approach would allow you to have the padding field in the module where you'd like to change the padding.
