WordPress provides a feature of maintenance mode that blocks the access and halts the functions during updates. In order to put your website under maintenance mode, you need to create a temporary page with a custom message on it. This will let your website visitors know that your site is down for maintenance.

To create a temporary page with a custom message, you need to follow the steps mentioned below:

1. Create a maintenance.php file
2. Add the custom message in maintenance.php file
3. Using <style> tag, apply styling (Theme styling is recommended)
4. Place the maintenance file in /wp-content folder
5. Add the following code in your Theme‘s functions.php file:
   
   add_action( 'wp_loaded', function() { global $pagenow; if( defined( 'IN_MAINTENANCE' ) && IN_MAINTENANCE && $pagenow !== 'wp-login.php' && ! is_user_logged_in() ) { header( 'HTTP/1.1 Service Unavailable', true, 503 ); header( 'Content-Type: text/html; charset=utf-8' ); if ( file_exists( WP_CONTENT_DIR . '/maintenance.php' ) ) { require_once( WP_CONTENT_DIR . '/maintenance.php' ); } die(); } });

   add_action( 'wp_loaded', function() {     global $pagenow;     if(         defined( 'IN_MAINTENANCE' )         && IN_MAINTENANCE         && $pagenow !== 'wp-login.php'         && ! is_user_logged_in()     ) {         header( 'HTTP/1.1 Service Unavailable', true, 503 );         header( 'Content-Type: text/html; charset=utf-8' );         if ( file_exists( WP_CONTENT_DIR . '/maintenance.php' ) ) {             require_once( WP_CONTENT_DIR . '/maintenance.php' );         }         die();     } });

6. Add the following code in wp-config.php file to enable/disable the maintenance mode:
   
   define('IN_MAINTENANCE', true);

   1	define('IN_MAINTENANCE', true);

You are done! Now, check your website URL. You will be redirected to a temporary page containing the custom message that your site is down for maintenance.
