Dequeue Scripts and Styles

By default, WordPress loads several styles and scripts that your site may not actually use. These extra assets slow down your page load unnecessarily. You can prevent WordPress from loading them by dequeuing them.

Example: dequeue Gutenberg

Gutenberg is WordPress's built-in block editor. Many users don't need it on the front-end — especially when they rely on a page builder instead.

Add the following code to your active theme's functions.php:

function dequeue_gutenberg_assets() {
    // Styles
    wp_dequeue_style('wp-block-library');         // Core block styles
    wp_dequeue_style('wp-block-library-theme');   // Theme block styles
    wp_dequeue_style('wc-block-style');           // WooCommerce block styles (if used)

    // Scripts
    wp_dequeue_script('wp-block-library');        // Core block scripts
    wp_dequeue_script('wp-editor');               // Editor scripts
}
add_action('wp_enqueue_scripts', 'dequeue_gutenberg_assets', 100);

How it works

• wp_dequeue_style() and wp_dequeue_script() — Tell WordPress not to load specific CSS or JS files on the front-end.
• Priority 100 — Ensures this code runs after all scripts and styles have been enqueued, so they can be safely removed.
• Result — Smaller page payload, faster load times, and fewer unused assets sent to your visitors — especially if you're not using Gutenberg.
