Bug - modal is fixed at top of page and displays improperly for long page

[anotherhale]

Elm.modal.1.mp4

Thinking about allowing the opening, opened, closing, and closed CSS functions to be configurable so that the client can provide their own CSS functions to resolve this issue.

Thanks a lot for this bug Andy. We totally overlooked it. Yes it could be possible. I think that we need some default setting anyway.

I just looked at the code and there is

1. a function modalFade: maybe it would be better here to remove Css.position, Css.top, Css.bottom, Css.left, Css.right and try to add something like Css.width (Css.vw 100) and Css.height (Css.vh 100)
2. a function setBodyFromTop which could help with some function to getting "viewport offset y position". Not sure if this getViewportOf could save us..
