A small js library that you can include in your project to get easy access to modern looking, strongly customizable message boxes that have a lot of functionality.
You can take a look at the demo page and look at the corresponding code and try to figure it out yourself how to use this library.
Or, maybe, just maybe, take a quick look at the documentation. 👀
I promise, it isn't that bad.
To embed the file into your project you could download it or use the following link:
