urgent CSS question

Sorry, but no one suggested a mailing list for CSS and the W3 Schools Forum has problems. This is the only reliable mailing list with professionals, so please excuse my off-path question as it is rather urgent. Why do I get completely different formatting with two identical classes? I want to change part of the formatting on just one page on the site using the exact same class with some changes so I don't modify other pages. I copied div#frame to div#frame1 and changed the class on the page to id="frame1". But now the page no longer displays the formatting as with id="frame" - e.g. <p> produces 16px font-size instead of 12px.
