Thanks to Vitaliy's wonderful hint ( How to make a non-standard column layout with Bootstrap? ), We almost managed to make the design as on the customer's layout, but it remained to align the headers (Tekst betaalpagina) in the center and left edge relative to the input. Please tell me how it can be done in a simple way for the whole form (which is done with tab switching) Thank you
