Comment box code

I can’t figure out how to add a comment section to my pages. I’m using the JS-Kit plugin form for my comments on my posts, but I’d like to add the form to my pages. In another post, someone said I need to edit the CSS code on pages.php, but I’m teaching myself CSS, and I don’t know exactly what to change or what code to input. The page I want to add the comment section to is here.

HELP PLEASE!
