Description
AlertsDLX offers beautifully styled alerts, callouts, and notification boxes for Gutenberg (the Block Editor), Full-Site Editing (FSE), the Classic Editor, or anywhere blocks and shortcodes are supported, including most page builders.
This plugin is a clean and modern timesaving solution to quickly adding customizable alerts, with a focus on being lightweight and user friendly.
Coupled with a free plugin like Block Visibility, your imagine can really go wild. For example, you can create an “Empty Cart” alert for WooCommerce or Easy Digital Downloads when a cart is empty. Create dismissible alerts for site-wide notices, or per-page notifications that can be dismissed.

Yes. It’s recommended to use a square image, and there is a built-in cropper available. Custom images look best center-aligned.

-
Can I show alerts on specific posts or pages?

AlertsDLX can be used in conjunction with free plugin Block Visibility to display a notification under certain conditions. While AlertsDLX in itself is not a site-wide notification tool, it can be used as one if put in a global template such as with FSE.

AlertsDLX does not support countdowns or auto-expiration. If you need an alert to auto-expire, I suggest using it with Block Visibility and setting a date-based visibility setting.

Yes, you can improve performance further by disabling the custom font supplied with AlertsDLX and supplying your own. Please see disabling custom fonts in AlertsDLX
