Easily add unlimited alert boxes for the new WordPress block editor. This includes dismissible alert notices.
This plugin works only in the Gutenberg/Block editor. Please use WordPress 5.0 and above or the Gutenberg plugin for pre 5.0 WordPress installations.

Simple Alert Blocks

Simple Alert Boxes are a nice elegant way to achieve quick alert styles within the block editor.

The code is well-done and lightweight and doesn't include too many fancy options.

In the future, I hope the author will consider more custom styling, but I suppose in order to keep the alert boxes simple, decisions over options is the right path here.

I have forked this plugin into something more advanced, so I am very intimate with the code in this plugin. Andrew hits it out of the park as usual.

Cheers,
