I create a button designed and animated on VS Code. It works. But when I tried to do the same with exactly the same CSS on Outsystems, the rendering is not working at all. Could you indicate me where I am wrong?

It is based on the tutorial you can find here:

I would appreciate so much some help, please. (cf. the file)

Thank you.
