cart and checkout pages can't show quantity/tota/ATM on iphone6 (safar, Chrome)

hi,
Doest anyone have tried latest i-craft theme(version 1.1.5) + wordpress4.5.2 + woocommerce2.5.5, cart and checkout page can’t work on iphone6 and iphone5(the same problem with safari and chrome)?
————– quantity part html —————
<div class=”quantity”>
<input type=”number” step=”1″ min=”0″ max=”” name=”cart[xxx][qty]” value=”2″ title=”” class=”input-text qty text” size=”4″>
</div>
——————————————–
Using iphone6 and iphone5 browser, quantity and price total are invisable.
Use iphone6 to check following link:
