animation-timeline-view header from kevin's video

I saw kevin's video about how we can customize the header after certain point when scrolling. I tried the same effect but the header stops sticking after a certain point. Code 👇

I'd recommend signing up for a codepen account (they're free, and support social logins iirc) and posting it in there so that it's easy for people to see in their own browsers how it's broken, it really helps to get answers

Melodium•3mo ago

yea, just now created it after hearing your advice in chit-chat https://codepen.io/ShiroCode69/pen/rNbELQe

I'll try to look later, though my night's pretty full. Hopefully someone else gets to it soon 🙂

You have your body height set to 100%. Try changing this to: min-height: 100svh;
