Dear all!
How it is possible to change the width of fields in registration and filter macros?
I would really love to make more information visible. To illustrate my question please see the following screenshot.

It should be somehow possible using the parameter input via CSS

I tried out using width: 1000px; but it seems that there is a limiting threshold. By using width: 10px; the form gets somehow smaller but not as small as 10px wide.
Much thanks for any hints in advance!
Stefan
