Add custom page design in Maintenance mode in Magento 2

We will learn how to add custom page design when Maintenance mode is active in Magento 2.

Firstly, make sure your website is in Default or Production mode.

bin/magento deploy:mode:show

Then enable the Maintenance mode by following command

bin/magento maintenance:enable

Once you enable the Maintenance mode following content will show up

Now in this example I will add an image and replace the above content.

You need to open 503.phtml file from following path – magento_root/pub/errors/default/503.phtml

<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
?>

<img width="100%" src="images/maintenance.jpg" alt="">

The images can be uploaded in the image folder in magento_root/pub/errors/default/images folder and style sheets can also be added in magento_root/pub/errors/default/css folders and can be used accordingly.

Happy Coding !
