fixed position GSAP Scroll Smoother + Fixed Footer (Curtain Effect)

[Christine-21]

Hello everyone!

I have been trying to figure this out for so long I decided to ask for help.

 

I'll try to explain the best I can, sorry in advance.

 

As the title says, I want to create a fixed footer. I know that we can't use that with scrollSmoother at least not if they are in the same container. 
I found a suggestion somewhere here that does the trick but you can't interact with the footer content.

 

My "solution" works well on desktop and footer is interactive, but on mobile the scrolling experience is really bad if not laggy and in some browsers (Opera GX) the footer height gets shifted.

 

Having the margin there might be a bad practice but it kinda works.

I'm at lost really i don't know how to figure this out while having interactive footer + smooth scrolling experience.

Footer has stylings of absolute and using as height the svh.

 

Thank you!

Without a minimal demo, it's very difficult to troubleshoot; the issue could be caused by CSS, markup, a third party library, a 3rd party script, etc. Would you please provide a very simple CodePen or Stackblitz that illustrates the issue? 

 

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best. See if you can recreate the issue with as few dependencies as possible. Start minimal and then incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen.

that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo: 

 

Using a framework/library like React, Vue, Next, etc.? 

CodePen isn't always ideal for these tools, so here are some Stackblitz starter templates that you can fork and import GSAP as shown in the Install Helper in our Learning Center : 

• React (please read this article!)
• Next
• Svelte
• Sveltekit
• Vue
• Nuxt

 

Please share the StackBlitz link directly to the file in question (where you've put the GSAP code) so we don't need to hunt through all the files. 

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions. ✅

Before I try to implement my solution into a demo, maybe you could give a solution to this existant codepen from an older post.

 

This works well on both desktop and mobiles, but you can't interact with the content.
