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.

<input id="test" type="number"/>

solution

Short answer:

input[type="number"]::-webkit-outer-spin-button,
input[type="number"]::-webkit-inner-spin-button {
  -webkit-appearance: none;
  margin: 0;
}
input[type="number"] {
  -moz-appearance: textfield;
}
<input type="number" />

To add to existing answer…

Firefox:

In current versions of Firefox, the (user agent) default value of the -moz-appearance property on these elements is number-input. Changing that to the value textfield effectively removes the spinner.

input[type="number"] {
  -moz-appearance: textfield;
}

In some cases, you may want the spinner to be hidden initially, and then appear on hover/focus. (This is currently the default behavior in Chrome). If so, you can use the following:

input[type="number"] {
  -moz-appearance: textfield;
}
input[type="number"]:hover,
input[type="number"]:focus {
  -moz-appearance: number-input;
}
<input type="number"/>

Chrome:

In current versions of Chrome, the (user agent) default value of the -webkit-appearance property on these elements is already textfield. In order to remove the spinner, the -webkit-appearance property’s value needs to be changed to none on the ::-webkit-outer-spin-button/::-webkit-inner-spin-button pseudo classes (it is -webkit-appearance: inner-spin-button by default).

input[type="number"]::-webkit-outer-spin-button,
input[type="number"]::-webkit-inner-spin-button {
  -webkit-appearance: none;
  margin: 0;
}
<input type="number" />

It’s worth pointing out that margin: 0 is used to remove the margin in older versions of Chrome.

Currently, as of writing this, here is the default user agent styling on the ‘inner-spin-button’ pseudo class:

input::-webkit-inner-spin-button {
  -webkit-appearance: inner-spin-button;
  display: inline-block;
  cursor: default;
  flex: 0 0 auto;
  align-self: stretch;
  -webkit-user-select: none;
  opacity: 0;
  pointer-events: none;
  -webkit-user-modify: read-only;
}
