Highlighting is on by default. To use a plain textarea instead, add this to your theme’s functions.php or a small custom plugin:

add_filter( 'postpage_sccss-highlight_code', '__return_false' );

This affects the Custom Code box on posts, pages, and products, and the default CSS fields on the plugin settings screen. Disabling highlighting uses a plain textarea. On posts, pages, and products, automatic syntax checking still runs for that textarea; the default CSS fields on the plugin settings screen do not have syntax checking.

If your theme or plugin renders products with the standard WooCommerce templates (wc_product_class() / content-product.php), registration is automatic. If you output your own HTML, register the product before rendering it:

do_action( 'postpage_sccss_register_product', $product_id );

You may pass a product ID, a WP_Post, or a WC_Product instance.
