Hi I'm currently working on a parallax website. I would like to add an image that moves down as the user scrolls...but ONLY within a section of a website. So 4 sections down..the image is there...it moves as the user scrolls down...then disappears behind 5th section and we see it no more.
I'm trying to do a similar effect to this website: Website
When you scroll down...you see "ABOUT" move between divs. I want to achieve that.
When I do it...it appears on top of first section and stays on screen all the way down.
Here's a sample JSfiddle. It only shows a part of the website: fiddle
I know it's to do with positioning. But I want it to stay within the DIV rather than positioned within the whole page.
// Create cross browser requestAnimationFrame method:
window.requestAnimationFrame = window.requestAnimationFrame
|| window.mozRequestAnimationFrame

|| function(f){setTimeout(f, 1000/60)}
var bubble1 = document.getElementById('bubbles1')
var bubble2 = document.getElementById('bubbles2')
var fish = document.getElementById('fish')
var scrollheight = document.body.scrollHeight // height of entire document
var windowheight = window.innerHeight // height of browser window
function parallaxbubbles(){
var scrolltop = window.pageYOffset // get number of pixels document has scrolled vertically
var scrollamount = (scrolltop / (scrollheight-windowheight)) * 100 // get amount scrolled (in %)
bubble1.style.top = scrolltop * .2 + 'px' // move bubble1 at 20% of scroll speed
bubble2.style.top = -scrolltop * .5 + 'px' // move bubble2 at 50% of scroll speed
fish.style.left = -100 + scrollamount + '%'
}
window.addEventListener('scroll', function(){ // on page scroll
requestAnimationFrame(parallaxbubbles) // call parallaxbubbles() on next available screen repaint
}, false)
window.addEventListener('resize', function(){ // on window resize
var scrollamount = (scrolltop / (scrollheight-windowheight)) * 100 // get amount scrolled (in %)
fish.style.left = -100 + scrollamount + '%'
