I needed to add a placeholder to a number input. Apparently this is only supported in Chrome.

The solution I found was to start with a text input with a placeholder and then on focus change it to a number.

<input placeholder="Amount" onfocus="this.type = 'number';">

So it will now have a placeholder until the input comes into focus.
