I am new to WordPress and am currently using Ninja Forms.
I would like to make the text boxes smaller and wondered if anyone could fill me in on how I do this using the Customer CCS Classes box (assuming this is what it is for?).
Also is there any way to add headings/instructions to the form other than using the label name?
I am aware that that there is a Layout & Styles Extension but I am keen to avoid additional costs at the moment.
