Locomotive + ScrollTrigger Pin Element Issue

Go to solution Solved by akapowl,

Recommended Posts

Hi everyone,


I'm having an issue when trying to pin an element using scrolltrigger with locomotive scroll. When I try to pin an element the width of the scroll proxy seems to get changed (or a scrollbar adrea added, I can't figure out which). You can see an example here:




I've also attached a screenshot. 913428129_Screenshot2021-11-15at18_14_02.thumb.png.51c3f4990572e25e0a76357389f2ab21.png


On all other pages the scroll container (.scroll-container) is 100vw.


I can't recreate the issue in my basic codepen either? I've set pinSpacing to false but is there anything else that could be causing this?


Many thanks in advance for any help

I don't really understand the question, sorry. And you said the CodePen minimal demo works fine, right? 


It's not feasible to troubleshoot a live site for free because there are so many other factors involved and we can't make changes and see results. Also please keep in mind that LocomotiveScroll is not a GreenSock product, so it's tough for us to support that. I glanced at the link you provided and I didn't notice anything odd but I'm sure I was just missing something obvious. Nice-looking site, by the way. 👍


If you still need some help, please provide a minimal demo the clearly shows the problem and we'd be happy to take a peek.

 Hi Jack,


Many thanks for your reply. Appreciate that it's hard to troubleshoot.


If you look at the screenshot of the site it seems to add a native scroll container to the page. It seems to only get added on the page with the pinned element. It's not that obvious but if you look at the page with the pinned element there's a border line and light grey background on the right of the page that isn't there on pages without the pinned element. If you look at the pen in full screen mode you'll see the difference where the width of the scroll container element doesn't fill the entire page. 


Hope that helps,


Thank you for the kind words about the site. As a greensock user since the flash days it means alot. You guys are amazing

Hello @mulegoat


Try adding overflow: hidden !important to the smooth-scrolling container.

That resolves things in the codepen demo for me. Maybe it'll help on your site, too.


.scroll-container {
  overflow: hidden !important;

Edit: ...and if you set the same to the body, you can also prevent a short flash of the scrollbar showing on load.
