Don’ts
Paul, a developer at Google, starts with the don’ts. Don’t use scroll events to create a parallax effect.

Trying to achieve a parallax look by changing background position doesn’t work well either, negatively effecting the animation.
CSS 3D
Paul recommends using CSS 3D for performant parallaxing, and gives detailed instructions for how to do just that. Anticipating the bugs for us, Paul includes various workarounds.
