input, type="number"

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 }

ich weiß aber nicht, ob das noch aktuell ist.

Eher nicht:

“Note: This specification intentionally refrains from making the appearance of all possible form controls and sub-controls available as values, as had previously been attempted by earlier proposals for this property and by several UA vendors in experimental implementations. […] Instead, this specification only provides 'auto', 'none'.” [CSS-UI-4]

Firefox kann die experimentelle Unterstützung von textfield jederzeit wieder fallenlassen.

Und WebKits/Blinks die experimentellen Pseudoelemente.
