Need name,email,website out of comment form

Hello WordPressers
I want to thank each one of you for your support, including those goof hearted ones that have helped me anonymously
on webpage: elcosito.com (twenty thirteen theme)
I got it NOT to diplay name,email and website from the visitors comments, thanks to reelevanssi, which is great
-what I would like not, is for the pages not to request (SHOW) name,email.and website on the area where the visitors can display their comments (items).
in other words just the comment box, that’s all, I think it is possible, and have been looking in the .css files but not sure were to make the change, any ideas, thank you in advance
