Edit forms code to change border

Hey all,
I would like to know if anyone has any tips for editing the Forms code? I would like the border to be 0.6 and at this point the editor will only allow a border of 1.
Thanks in advance!

@Alana_Lenz have you check this article? I have not personally try this but I guess it would go like this:

  1. Find the ID of the form
  2. Write a new CSS rule (probably with !important) that will overwrite the default form style.
