Broken parallax scrolling effect (only works if you wiggle your mouse over the dweet while you scroll the page)

u/joeytwiddle

I tried various things but I couldn't find any way for the iframe to know when it has been scrolled. :-/
u/katkip

It impossible. Iframe's cursor doesn't update if mouse isn't moving inside iframe
