How do I move [other] option text box upward?

In my css, i tried to set the top margin to be negative, but no matter what values i put in, the box just won't move. Please help, thanks.

Please try the next CSS:

label[for=other_19] {
display: none !important;
}
.form-radio-other-input {
max-width: 160px;
margin-left: 3px;
}
