Step 2 - Template > Text Style

Field / Button: these are the fields and buttons in the forms that are created with the Contact Form Object, the Search Object or the e-commerce shopping cart, the login/logout fields of the Members' Area, etc. When you create a new Contact Form Object the fields and buttons in it take on the style defined here by default. You can subsequently change the style of a particular form using the options in the Contact Form Object | Style section.

... or you can solve it immediately with this code:

<style>
#imObjectForm_28_buttonswrap input{ margin:5px !important}
</style>
