Hallo, can anybody please tell me where I can find the content of these classes: .ui .form ?

Hi Rita,

You can over-write them using a Load CSS action in your form. That is simpler than editing the CSS files directly.

Thank you Bob, I agree with you - I also read about this - but was unable to find the Load CSS in the Setup form functions.

I would actually have 2 more questions - can I ask them straight away ? or do I need to open a new topis ?

very kind regards
Rita
