For situations when NOT using WooCommerce plugin, you will need to manually put styles in Theme Options>General>Display>CustomCSS box to style these 3 boxes well.
Notes:
Default styling is written in woocommerce.css file which only triggers when WooCommerce plugin is installed.
'YOURWEBSITE' should be replaced by your original URL.
