Why my Hide Banner Function doesn’t works?

#banner { position: absolute; top: 30px; text-align: center; font-size: 3em; width: 100%; z-index: 10; } .fadeout { visibility: hidden; opacity: 0; transition: visibility 0s 4s, opacity 4s linear; }

The banner must be hidden from the JavaScript code, see: shapespark-viewer-api/body-end.html at master · shapespark/shapespark-viewer-api · GitHub

My code is exactly like this, but unfortunately it doesn’t work.

This code has to be placed at the end of the <body> element, not <head>, because in <head> Shapespark’s JavaScript code isn’t loaded yet.
