Need advice on how best to do this!

[Britangie1]

I have a news page which runs to several very long pages which is a pain to update as I insert new content at the top of the current page and have to push everything down and faff moving images and content around. Is there a way to create a page where the content would scroll downwards so I can insert more at the top without having to lengthen the page or move things around? Im not sure if I've explained it very clearly?! I have webdesigner premium 12. I've had a look at the widgets and I couldn't see anything I could insert into a page to use. (Though I might be looking in the wrong place!)

Any help would be great and help my sanity.
