Original solution won't work anymore. The spinners are part of shadow dom. For now just to hide in chrome use:

input[type=number]::-webkit-inner-spin-button {
  -webkit-appearance: none;
}

or to always show:

input[type=number]::-webkit-inner-spin-button {
  opacity: 1;
}

You can try the following but keep in mind that works only for Chrome:

input[type=number]::-webkit-inner-spin-button { 
    -webkit-appearance: none;
    cursor:pointer;
    display:block;
    width:8px;
    color: #333;
    text-align:center;
    position:relative;
}

input[type=number]::-webkit-inner-spin-button:before,
input[type=number]::-webkit-inner-spin-button:after {
    content: "^";
    position:absolute;
    right: 0;
}

input[type=number]::-webkit-inner-spin-button:before {
    top:0px;
}

input[type=number]::-webkit-inner-spin-button:after {
    bottom:0px;
    -webkit-transform: rotate(180deg);
}
