the can should be fixed while scrolling.
in addition after 20%, 40%, 60%, 80% of filling additional text-icon combinations should popup, but i guess that should be pretty easy once i've figured out how to control the filling.
the revealing has to be done by using a mask, because with a png on top i'd also hide parts of the cans frame. My skills in html/css are pretty decent, but i've never worked with svg masks before. Do you know if there's a sample i could use as starting point?
many thanks in advance
