styling shopping cart page

Hello everyone,
i’m new to woocommerce and i’m trying to style shopping cart so that upsells products will display right next to the contents of the cart.
i’ve used the following css but i can’t figure out how to move it up
any help would be much appreciated

/* shoping items */
.woocommerce table.shop_table {
width:48%;

}
/* cart totals */
.woocommerce .cart-collaterals .cart_totals, .woocommerce-page .cart-collaterals .cart_totals {
float:left;

}

.woocommerce .cart-collaterals .cross-sells, .woocommerce-page .cart-collaterals .cross-sells {
float:right;

}

.add_payment_method .cart-collaterals .cart_totals table, .woocommerce-cart .cart-collaterals .cart_totals table, .woocommerce-checkout .cart-collaterals .cart_totals table {
width:100%;

}
