Hello,
Disable this option https://prnt.sc/FcLVNFvST1Ov and use the next custom CSS code:
.single-product-builder .single_add_to_cart_button ~ .et-or-wrapper {
flex-basis: 10%;
margin-left: 10px;
margin-right: 10px;
}
.single-product-builder form.cart {
display: flex;
}
.single-product-builder .et_product-block .et-single-buy-now.single_add_to_cart_button.button {
width: 20%;
flex-basis: 20%;
min-width: 20%;
}
