WooCommerce: Add a Continue Shopping button to Single product, Cart and Checkout pages.

I decided to create a separate tutorial for adding a Continue Shopping button to multiple pages.
The following example uses the theme Twenty Twenty Two.

// Add continue shopping button to Single product page, Cart page and Checkout page.

/* Single product
https://www.businessbloomer.com/woocommerce-continue-shopping-button-single-product-page/
https://www.businessbloomer.com/woocommerce-visual-hook-guide-single-product-page/ */

add_action( 'woocommerce_after_add_to_cart_button', 'continue_shopping_button_to_single_product' );
function continue_shopping_button_to_single_product() {
 $shop_page_url = get_permalink( woocommerce_get_page_id( 'shop' ) );
 echo ' <a class="continue button" href="'.$shop_page_url.'">Continue Shopping</a>';

}

/* Cart
.https://wpbeaches.com/add-continue-shopping-button-woo-commerce-cart-page/
https://www.tychesoftwares.com/woocommerce-cart-page-hooks-visual-guide-with-code-examples/ */

add_action( 'woocommerce_cart_actions', 'continue_shopping_button_to_cart' );
function continue_shopping_button_to_cart() {
 $shop_page_url = get_permalink( woocommerce_get_page_id( 'shop' ) );
 echo ' <a class="continue button" href="'.$shop_page_url.'">Continue Shopping</a>';

}

/* Checkout
.https://www.businessbloomer.com/woocommerce-visual-hook-guide-checkout-page/
https://gist.github.com/bradleysa/7d1448253097784daf94 */

add_action( 'woocommerce_review_order_before_submit', 'continue_shopping_button_to_checkout' );
function continue_shopping_button_to_checkout() {
 $shop_page_url = get_permalink( wc_get_page_id( 'shop' ) );
echo ' <a class="continue button" href="'.$shop_page_url.'">Continue Shopping</a>';

}

The CSS:

a.button.continue {
	background-color: var(--wp--preset--color--primary) !important;
	padding: 0.8rem 1rem !important;
        border: 2px solid #ebe9eb !important;
        margin: 0;
	color: #fff !important;
}
