Hello,

Email field type is one of Form controls contrary to simple TextBox field. The inline controls are enveloped by <div> because it may not access inside the code of form control.
If you would like to style the form controls directly – e.g <input class=”xxx” … you would need to re-write the code of that form control. Their sources are stored in <web site folder>/CMSFormControls by default.

Best regards,
