Hi,
Please start your modifications using this:
Remove Dividers:
.woocommerce-account p.myaccount_address, .woocommerce-account .page-content h2, p.no-items, #order_review table.shop_table, #payment_heading, .returning-customer a, .woocommerce #payment ul.payment_methods, .woocommerce-page #payment ul.payment_methods, .woocommerce .coupon, .summary-top {
border-bottom-color: transparent!important;
}
.sf-share-counts {
border-color: transparent!important;
}
Remove Quantity:
.woocommerce .has-no-sidebar div.product form.cart div.quantity {
display: none;
}
Center Product Text:
.single-product.page-heading-fancy .product-main {
text-align: center;
}
Center Product Add To Cart Button:
.woocommerce div.product form.cart .button {
float: none;
}
Regarding your overlapped image screenshot, I do not understand that. There are no overlapped images from what I can see.
