Website is not Centered in Browser Window

[Gibsonriver2]

Hello:

I have a problem where when I publish my website 2 pages are not centered. They are left justified in the web browser. If I do a preview, the pages display correctly. I have had this problem before and what I have done is create a blank page and copy and paste the "defective" page content to the blank page. This seems to work but has not always worked.
If anyone has any idea as to what I have done wrong, and a fix, it would be much appreciated.

Sincerely,

Ingo

Gr2, you may have not properly ended some code in a Placeholder.

As it is a form, I think this will be the case.
