Parallax with CSS only

This 8 layers vertical parallax is made in Webflow with some line of custom CSS code. No Javascript. 

All the images are SVG. The method is long and has some downsides, requires a few fine tuning. And you can’t really control the length of the final page. I don’t recommend this method for a full production site. It’s more an experiment. You can duplicate this site and analyse the settings. Below is the custom CSS code added to the site’s dashboard. 

<style>
/* CSS Vertical Parallax */
* { -moz-box-sizing: border-box; box-sizing: border-box; }
.parallax-e3 {-webkit-perspective: 100px; perspective: 100px; height: 100vh; overflow-x: hidden; overflow-y: auto; position: absolute; top: 0; left: 50%; right: 0; bottom: 0; margin-left: -50%; }

.layer-p1-e3 { -webkit-transform: translateY(-1000px) translateZ(-600px) scale(7); transform: translateY(-1000px) translateZ(-600px) scale(7); }
.layer-p2-e3 { -webkit-transform: translateY(-1200px) translateZ(-500px) scale(6); transform: translateY(-1200px) translateZ(-500px) scale(6); }
.layer-p3-e3 { -webkit-transform: translateY(-50px) translateZ(-200px) scale(3); transform: translateY(-50px) translateZ(-200px) scale(3); }
.layer-p4-e3 { -webkit-transform: translateY(210px) translateZ(-150px) scale(2.5); transform: translateY(210px) translateZ(-150px) scale(2.5); }
.layer-p5-e3 { -webkit-transform: translateY(240px) translateZ(-100px) scale(2); transform: translateY(240px) translateZ(-100px) scale(2); }
.layer-p6-e3 { -webkit-transform: translateY(54px) translateZ(-50px) scale(1.5); transform: translateY(54px) translateZ(-50px) scale(1.5); }
.layer-p7-e3 { -webkit-transform: translateY(38px) translateZ(-25px) scale(1.25); transform: translateY(38px) translateZ(-25px) scale(1.25); }
</style>

The structure in Webflow is as follow:
