I have been struggling with this for a long time: how to show a message (e.g. inside a box) on a fixed position within the VIEWPORT, not the page?
"Pinning" would work, but ..... it doesn´t work on mobile. Ideally, I am looking for something like an extra argument to a $w-box as in "vp_center", "vp_luc", "vp_ruc", "vp_llc", "vp_rlc".
(= left/right/upper/lower corner or, default, center, all within ViewPort)
I know I can use LightBoxes, but communicating with them is a pain AND they take too long to load.
Any suggestions would be much appreciated.
