Rellax.js mentions (4)

  • Parallax scrolling: JS or CSS?
    If you want something lightweight but at the expense of strict accuracy, I like the flexibility of Rellax. Source: almost 4 years ago
  • how to create scrolling where only text and image move and not the page?
    Relax (for parallax scrolling speed of elements). Source: over 4 years ago
  • [AskJS] Simple Smooth Scrolling. Why is no library doing this?
    Scroll-based interaction or animations have been popular for quite a while now. But most of the libraries I find either disable the browser scrollbar completely and implement their own scrolling based on css transforms (like locomotive-scoll) or dont touch the native browser scroll at all (like rellax or lax.js). Source: almost 5 years ago
  • Very cool web design on this article... "Why almost everything you thought about running is wrong"
    I'm on mobile so I can't see the source but I'm pretty sure it's just parallax, you can just use something like https://dixonandmoe.com/rellax/ to make something very similar. Source: about 5 years ago
