Remove spin buttons from number input field

Stumble upon this piece of CSS:

// remove spin buttons from number input field
input::-webkit-outer-spin-button,
input::-webkit-inner-spin-button {
    /* display: none; <- Crashes Chrome on hover */
    -webkit-appearance: none;
    margin: 0; /* <-- Apparently some margin are still there even though it's hidden */
}
input[type=number] {
    -moz-appearance:textfield; /* Firefox */
}

Poor Chrome :D Hope this is fixed since ages.
