Hide seconds when using datatype 3.byte time/day

[cdebackere]

Add this to Custom CSS:

Code:

123456789

.timepicker-day, .timepicker-second {   display: none; } .timepicker {   margin: 10px 0;   display: flex;   justify-content: space-evenly; }

I hoped to use this 'conditionally', so only on certain timepickers with an additional class,
but embedding this code in a construct like .hourMinPick {...} does not work. HOw should that be written?
