Hello,
Thanks for the reply.
Code that causes it comes from Elementor and jet-woo-builder plugins – https://gyazo.com/968707796303575ab895d2ade6f72f0b , so contact the support of plugins to get assistance.
Or use the next custom CSS code
.single-product .product .elementor-jet-single-add-to-cart .cart .quantity .input-text {
width: auto;
max-width: 45px;
}
.single-product .elementor-jet-single-add-to-cart .cart .quantity {
display: flex !important;
width: 93px !important;
float: left !important;
}
Regards
