[data-input][type="number"]::-webkit-inner-spin-button, 
[data-input][type="number"]::-webkit-outer-spin-button {  
   -webkit-appearance: textfield;
    -moz-appearance: textfield;
    appearance: textfield;
}

input[type=number]::-webkit-outer-spin-button, 
input[type=number]::-webkit-inner-spin-button {
    -webkit-appearance: inner-spin-button !important;
}

input[type='number']::-webkit-outer-spin-button,
input[type='number']::-webkit-inner-spin-button {
   -webkit-appearance: inner-spin-button;
   opacity: 1;
