I was look for .twig file or section in admin panel but didnt find nothing.
I want to change layout in this iframe.
OpenCart version 3 on the twig.
Thiss button for call iframe:
<a class="btn btn-cart"
data-toggle="tooltip"
data-tooltip-class="module-products-27
module-products-grid cart-tooltip"
data-placement="top"
onclick="cart.add('360', $(this).closest('.product-thumb').find('.button-group
input[name=\'quantity\']').val());"
data-loading-text="<span class='btn-text'>Buy</span>"
data-original-title="Buy"><span class="btn-text">Buy</span>
</a>
If you whant replace text, icon and style:
Cart button text you will find in language file catalog/language/en-gb/en-gb.php, line
$_['button_cart'] = 'Add to Cart';
PRODUCT PAGE
Icon and setting of this button you will find in
Journal > Styles > Product Page > DEFAULT
On this setting page find Buttons > Add to Cart
PRODUCT GRID
Icon and setting of this button you will find in
Journal > Styles > Product Grid > DEFAULT
On this setting page find Buttons Group > Add to Cart
