Adding some CSS using wp_footer hook doesn't work

To make the WooCommerce product image "display" the right way, I'm using CSS by usig the wp_footer hook. This way, the product thumbnail is displayed correctly on the checkout with margin, etc.

Code:

add_action( 'wp_footer', 'ls_product_image_css_checkout', 900 );
function ls_product_image_css_checkout() {

    // run only on checkout
    if ( is_checkout() ) { ?>

        <style>
        .product-item-thumbnail{ float:left; padding-right:20px; }
        .product-item-thumbnail img{ margin:0!important; }
        </style>

    <?php
    }
}

Now, here is my REAL problem and YES, I have tried various CSS solutions since the product removal has a <a class="" and yet, no matter what I do - the X for removing the product from checkout is displayed on the right of the thumbnail, directly next to the Product Name.

I need the X for removal to be placed on the LEFT of the thumbnail.

This is the code I am using:

add_filter( 'woocommerce_cart_item_name', 'ls_product_removal_on_the_left_of_product_image_on_checkout', 20, 3 );
function ls_product_removal_on_the_left_of_product_image_on_checkout( $product_name, $cart_item, $cart_item_key ) {

    // only on checkout, of course
    if ( is_checkout() ) {

    // get cart
    $cart = WC()->cart->get_cart();

        // loop through cart
        foreach ( $cart as $cart_key => $cart_value ) {

            if ( $cart_key == $cart_item_key ) {

                $product_id = $cart_item[ 'product_id' ];
                $_product = $cart_item[ 'data' ];

                // this is part of what I cannot figure out
                $remove_product = sprintf(
                '<a class="rpfc" href="%s" title="%s" data-product_id="%s" data-product_sku="%s" data-cart_item_key="%s">&#10005;</a>',
                esc_url(wc_get_cart_remove_url( $cart_key)), __( 'Delete this product from my order', 'woocommerce' ),
                esc_attr( $product_id ),
                esc_attr( $_product->get_sku()),
                esc_attr( $cart_item_key ));
            }
        }

        // get product data
        $product = $cart_item[ 'data' ];

        // display the iamge on checkout, 40*40 px
        $thumbnail = $product->get_image( array( 40, 40 ) );

        // the HTML
        $image_html = '<div class="product-item-thumbnail">' . $thumbnail . '</div>';

        // get the product name and link it. If clicked, re-directed to the product page
        $product_name_link = '<a href="' . $product->get_permalink() . '">' . $product_name . '</a>';

        // the removal of the product BEFORE the image
        // REMOVAL (on the left of the image) IMAGE PRODUCT NAME
        $product_name = $remove_product . $image_html . $product_name_link;
    }

    return $product_name;
}
