Playground
One example, and every option that changes what you see. Change one thing, zoom in and out, and the code below shows the line you need. Nothing else.
Nothing set is the default. The code shows only what you changed.
How to use it
Change one thing at a time and zoom in and out a few times. Motion comes first: once duration and ease feel right, the rest is a layer on top. Every option here can also be set on a single trigger with a data-with-* attribute, so one zoom can behave differently from the others. The API reference lists them all.
