How to hide pages

I am taking my temp site public tomorrow – http://23c.1c7.myftpupload.com/ However, I have created certain HTML pages on the site I do not want people to find or see. I don’t want to delete them because I may use them later. Do you have any suggestions how to do this? Thank you.

How do you hide answer on Q&A page until it's clicked on?

Is there a way, on my Q&A page of my site, to have my questions visible, but my answers hidden until someone clicks on the letter A, or clicks on the first few words of the answer, and then it expands and shows the entire answer?
