Hello, Steve.li.vt,
Thank you for the reply.
You find out that the code that stretches container – max-width: 100%; causing the problem, it is what we told you before. Your custom code causes the problem, so would not recommend to use this code:
.single-product .content-page.container {
max-width: 100%;
padding-left: 0;
padding-right: 0;
}
As a workaround, edit single-product.php (xstore/woocommerce folder) via child theme. Keep only content-page class of this div -> https://prnt.sc/fcRkmNkWC3mo
and test without your custom CSS
It means that container styles will not be applied to your single products and the page will be stretched on the first load initially without any CSS additions.
Kind Regards,
