boostrap required input override to remove red

required.scss

//make an 'invalid', required input look like a normal form field
//with plain bootstrap, this field shows up as red before the user has submitted the form
//ideally,it would not be considered :invalid until after the form has been submitted 
//alas, this is not currently the case

input:focus:required:invalid, textarea:focus:required:invalid, select:focus:required:invalid {
  color: #555;
  border-color: $inputBorder;
  &:focus {
    border-color: rgba(82,168,236,.8);
    @include box-shadow(#{inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(82,168,236,.6)});
  }
}
