Loop-page.php and complete reinstallation

Hi there, Thank you for your reply. I have done the following:

Using FTP (Filezilla)

I created a directory under wp-content/themes. I called it twentyten-child. I am lost at how to create the css file. I know that I can use notepad and I read your link. It says I need to copy this text below: (however I am lost at what to change/edit) By the way the name of my site is http://www.tc-p65vt50review.com. Can you direct me further and tell me what I need to edit in the css file. Thnaks so much
