I use 2 external CSS files and Reference as Follows: <Link Rel="stylesheet" Type="text/css" href="old.css"> <Style type="text/css">@import url(new.css);</style>
This was a life-saving tip for me; a lot of the people I'm trying to reach work in government agencies, schools, etc. with antique equipment. Now I can finally use positioning without having the columns overlapping each other in NN4. The columns end up one after the other, but at least it's readable.
