The Problem
Our designer has been working with the frankly amazing plugin Slider Revolution for years, but like a lot of powerful tools it delivers the bloat in boatloads. We were using Revolution Slider to create an appealing parallax effect on our homepage, but once we added in the needed tools for SEO and UX tracking the performance was unacceptable for a company that sells optimization as one of its core pillars of web design. We optimized around it for a good long time, but a recent update broke our responsive styling and it just became too much friction for us to work around.
We wanted the maintain the effect but still gain a bunch of speed.
