Thanks to Rachel Nabors for pointing us to Paul Lewis’ excellent article on Performant Parallaxing. This article is so useful, we couldn’t pass up the opportunity to recommend it. Continue reading for a quick summary or head over to Paul’s article right away!
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.
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.
