Could be a thousand things (margin, padding, floats etc) and unfortunately screenshots don't tell us much (other than there's a white line).
Can you post a link to the page?
It's not live yet but I can make it live.... it' nowhere near complete is the reason it's not live
i tried to post it but because the file name isn't index.html, but is rather
index.dwt.asp, it doesn't seem to post live like a regular html
Can anyone help?
