Hi Jade. This was not what I am looking for. Is it possible to define each of the three columns by different values, e.g. 45% 30% 25%? Thank you again.
Hello Prasant. Thank you so much. Yes it works fine. I have one additional question: With reduced screen width, the baseline of the text moves down. Can this be corrected? I made a screenshot https://www.danielhurter.ch/screenshot-form01.jpg . Thank you once again.
