javascript - Can I hide the HTML5 number input’s spin box?

Is there a consistent way across browsers to hide the new spin boxes that some browsers (such as Chrome) render for HTML input of type number? I am looking for a CSS or JavaScript method to prevent the up/down arrows from appearing.

Answer

This CSS effectively hides the spin-button for webkit browsers (have tested it in Chrome 7.0.517.44 and Safari Version 5.0.2 (6533.18.5)):

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 */
}

You can always use the inspector (webkit, possibly Firebug for Firefox) to look for matched CSS properties for the elements you are interested in, look for Pseudo elements. This image shows results for an input element type="number":
