remove cart, count and tooltip

I am trying to remove the cart icon, count and tooltip using css, so that site visitors will access their order from the cart page. I am using customizr theme and have tried the following which sometimes works on desktop, but not at all on mobile:
/* remove cart icon */
.icn-shoppingcart {
display: none;
}

/* remove cart item count */
.czr-wc-count {
display: none;
}

/* remove tooltip */
.woocart.cart-contents {
display: none;
}
