How can I modify the css of a divider and of a text box

I would like to modify the padding of the divider and text box that show up on my form when I select the option "I'm the renter". However, I cannot find the field ID for these two elements. How can I modify the CSS for those two elements?

Hi there,

I've checked your form and it's id_31, so for example:

#id_31 {

  padding: 30px;

}

Please give it a go and let us know if you have further question.s
