Show content in a modal after page load.
Usage:
Select ‘SN Popup’ from the admin menu, then Add New. Type a name for the popup and insert any content you like. If you’re done, click Publish.
Now find a page or post you’d like to see the popup on and edit it. There should be a new metabox called ‘SN Popup’, choose the settings you want and hit Update, then view your page.

To change the styling of the modal, you can override its styles in your theme’s css. Or for more advanced styling you can dequeue the default css and replace it with your own.
For reference, the default unminified version of the css is located at /plugins/sn-popup/vendor/featherlight-1.3.4/src/featherlight.css
To dequeue the old css and enqueue your own, add something like this to your functions.php:
<pre><code>add_action('wp_enqueue_scripts','remove_featherlight_css'); function remove_featherlight_css(){ wp_dequeue_style('sn-featherlight'); wp_enqueue_style('featherlight-new-css','/path-to-new-css'); } </code></pre>

This small plugin allows you to create a modal / popup / lightbox with WordPress’ default Block editor (Gutenberg). The plugin provides you with a block that can be used for the modal’s trigger and the modal’s window contents. Anything you can do with the block editor, you can use for the modal trigger or the contents.
<ul>
<li>Multiple trigger methods. Use the power of the Block Editor to create your trigger (buttons, images, covers, and more).</li>
<li>Flexible modal content. Similarly to the trigger, use the Block Editor to define the content inside your modal content.</li>
<li>Supports multiple modals on the same page.</li>
<li>More to come.</li>
</ul>
To create a modal, simply use the Modal Builder block to create a trigger. Use another Modal Builder block to create the content (make sure you select the appropriate content type under the modal settings). On both instances, set the “Content ID” to whatever you want as long as both instances match. You are set.
