Fade-in background image

[Anjar]

Hi all,

I tried to make a single tiddler view where the background image changes when you change tiddler, and it works okay: https://andjar.github.io/TiddlyMenu/lighthouse.html

However, the transitions are a bit harsh, so I wondered if it would be possible to add a transition/animation (e.g. fade)? Since CSS seems to be restrictive regarding background animation (?), would it be easiest to modify zoom.js? Any experiences?

Best,

Anders
