I'm trying to do some scrolling in JS. What i want is when i spin my mouse wheel my page should scroll down by one element. Elements are full screen, so basicaly i want vertical carousel.
My div elements have 100vh so when i resize window it should scroll by the height of the window.

document.addEventListener("wheel", function(event){
    if(event.deltaY<0)
    {
        window.scrollBy(0, -window.innerHeight);
    }
    if(event.deltaY>0)
    {
        window.scrollBy(0, window.innerHeight);
    }
});

I found this code on internet. When I scroll it flickers, it moves window as I want for a milisecond and gets it back where default scroll position is (20px or w/e the number is). Thanks in advance!
