Change Block Cart background color when cart has products

[teoB_Glar]

Hi,

can anyone point me to a direction how to change Block cart's background color when a customer adds products to cart? Can I make this modification through css? How can I check if cart's items>0?

 

Best regards

you're talking ablout block user info short information about cart, or about cart visible after "on mouse over" effect?

anyway. in both modules you can use if condition: {if $cart_qties == 0}{/if}
