Currently, they are moving all the time, by keyframes in CSS but it's not that what I want. I want them static and move some distance after scroll. For example: they are static -> scroll -> first line from left goes up by 100px, second line from left goes down by 80px, third goes... etc And i want to define these distances for each of them or that can be totally randomize but in the range in which I specify.
I guess I'll have to use JS, but i'm still learning this
Here's the example what i want to do: https://crafton.eu/portfolio/ergo-hestia/
Not sure if that's what you are kinda looking for? I attached the fiddle link .

JS:
$(window).on('scroll', function() {
var line3top = $("#line_3").offset().top;
console.log(line3top);
$("#line_0").css('top', "+=" + 10);
$("#line_1").css('top', "+=" + 5);
$("#line_2").css('top', "-=" + 3 + "px");
$("#line_3").css('top', "+=" + 3 + "px");
$("#line_4").css('top', "-=" + 10 + "px");
$("#line_5").css('top', "+=" + 4 + "px");
$("#line_6").css('top', "+=" + 15 + "px");
})
