How to code in css fabrikElementContainer---?---field ?

[blue-mouse]

Hi,

I need to make custom form template that is something sophisticated.

I try modify form that is one_column---form, but for 2 fields at top of my form i need make:
li.fabrikElementContainer #ccjom_cc_kk_karta_rejestr___field_display1
{width:40%; background-color: lightblue;}

li.fabrikElementContainer #ccjom_cc_kk_karta_rejestr___data_przyjecia
{width:55%; background-color: lightgrey;}

so, i suppose the idea what i need is clear, but code is not correct

Can anyone help me with this?
