Hi. First of all, is it necessary to add captcha or re-captcha fields to the forms of my website or is there an already integrated spam-protector in the forms?

2. I try to apply a re-captcha on my small form, but it appears that re-captcha is not very css friendly nor mobile-friendy since its within an iframe. So it exceeds my page borders. Is there an easy solution to this? e.g. css styling? Ive attached 2 images of the issue.

Kind regards
