Have a look at the source code of a preview in VSD see the position absolute statements. I use the editor and all elements I wish to insert are placed that way, Forms, tables,Iframe's, Links, Images. php injection, Some standard html is needed from time to time but when I want an element to be precisely in position That's what I do.
Coffee (The Editor) becomes a better VSD than VSD but with a few extra delights under its belt. Actually I believe you need both, they go together like peaches and cream. Add the form builder and the Web Image Studio learn a bit of php and there is literally nothing you can't do with it.
I have only been playing with this gear for a year and I am starting to see the logic that makes it tick. Added to this forum and well it doesn't get any better
