Is it possible to create a draggable window in Velo?

Hello,

I’m new to Velo. Is it possible to create a draggable graphic? I want to recreate a classic looking Windows 95 message box that can be dragged around.

I’ve found examples like this: https://codepen .io/Vovastradamus/pen/JjqjPB
however, my understanding (so far) is the JavaScript used needs to interact with CSS classes, which doesn’t seem possible in Velo.

Cheers.
