credit card number field too long on mobile

I made a quick fix on payment.php replacing the 400px with 100%. Don’t know if that’s the best, but it worked. Maybe just needs to be removed.

<input class=”input-text” type=”text” size=”19″ maxlength=”19″ data-stripe=”number” style=”border-radius:6px;width:100%;”/>
