Aligning fields in forms

Site URL: https://www.economichire.com/request-staff

I want to line up fields in my form. I want it to be position type next to job function, position hiring for next to zip code, and email next to business phone. I know its a matter of custom css but nothing I have found so far is working. Any help is greatly appreciated.

<style>
.form-wrapper .field-list .field:nth-child(-n+5) {
    width: 45%;
    margin-right: 2%;
    float: left;
}
  .form-wrapper .field-list .field:nth-child(6) {
    clear: left !important;
    width: 100%;
}
</style>
