Hi Alicia
This didn't work for me at all, however, this one did:
.mktoRadioList.mktoHasWidth {
width: 400px !important;
}
.mktoRadioList input, .mktoRadioList label {
float: left !important;
}
.mktoForm .mktoLabel {
float: none;
}
.mktoFieldWrap span{
display:block;
}
I don't know why this isn't an option with Marketo forms, i had the same issue with the old version also.
good luck
Lauren
