Why is not there an animation?

[AlexPaskal]

Hello! Thanks you for your library! It is very good and useful.

But on your site there is an animation when alert close. But when I use library there is not it. What can I do? (I use the last version, now it's v1.0.11).

Thanks you, and excuse me for my mistakes.

Are you using Bootstrap by any chance (or other CSS styles affecting .show and .hide classes)?

#116 helped me, it might help you too.
