OK, good to know.
My fields span the container, which makes my form seem long. Many of the fields I can shorten to a % to get 2 on a line.
However, I began doing this and now my field labels are all vertically stacked on one side of the screen - not neatly lying above each field like they were. How can I adjust that? Anyway field label can 'know' to stay linked to its corresponding field?
