Add css class name to next/previous/submit

Hi,
is there a way in 2.9 to attache a css class name to
buttons:

  • next
  • previous
  • submit
    Its easy for form fields. but cannot find it for buttons.

when starting multiple page forms, there are the following fields that can have there own css

  • start pagination
  • next page
    but that ones are not for the submit/next/back buttons.

I know how to style buttons with custom css, but want to add the theme button css style

You can do this using the gform_submit_button, gform_next_button, and gform_previous_button filters in the theme functions.php file, a custom plugin, or a code snippets plugin. See this example.
