JavaScript Sticky

hello everyone,

i have written a page with a video sync on scrolling but i'd like to get my sections sticky until the next one

  • i followed this tutorial : https://www.youtube.com/watch?v=HiegEfkenXA and used his sticky function but it doesn't work and I don't understand why...
  • And then do you know how I can stop that for my next (big) section ? where its written in comment section 2 - previ in the hilt part, I'd like to go on another style and background but I don't really know how to indicate that the video need to stop display when meeting this (big) section 2 - previous.
  • I used also the selector section in my script (in the html part), can it be a problem if I need to do other sections on the page that will not be linked to this ? (I supposed that I can use class...)

thank you so much for your help and time :)
 
Try changing position: relative; in the section styling to position: sticky; and then add top: 0px;.

See it that works and let me know.
 
hello, thank you for your help, it works !

but the text is just covering each other doesn't look like it disappearing, at least for the .content section, do you know how to fix it ?

Capture d’écran 2022-08-04 à 01.53.22.png

and do you know why my video keep being the background of my site ? I'd like that it stop after the script and before section 2 - previ in comment

thank you so much for your time and your help, it really helps me !
 
Sorry, was busy running around and packing the house yesterday (we're relocating). so maybe I'll try today then, if I won't be busy again.
 
Hey johna, no probs, I've been busy on blender so I let the website on the side for the moment, tell me if you found the problem !
thank you for your help, I hope that everything gone well during the relocation :)
