ScrollTrigger animated height with end value issue

Go to solution Solved by akapowl,

Recommended Posts

In the pen the height of the header is updated on scroll, but the value for end stays the same.(I coloured the header so you can see it better that the end value is not at the bottom of the header after it changed height). How can I update the end value constatly so this does not happen? (I hope you can understand what I mean)

Hello there, @Jona Anders

 

For performace reasons, ScrollTrigger does all its calculations upfront - so it won't change the start and end while you change the height of an element that you have a ScrollTrigger on when you're scrolling.

 

There was a similar question just recently, that might help you get in the right direction.

 

 

 

 

Here's what your example could look like then - unfortunatelly, if I am not mistaken, I don't think you can use values like rem for the end of a ScrollTrigger, so you'll probably have to do the neccessary calculation based on the window's height and pixels instead.
