Can you please tell me how to make a horizontal animation that works synchronously with the scroll?
I made a sample, but there is a drawback - the event has a start and end point, and I want to make a permanent animation:
const targetTx = document.querySelector('h1');
function animateTx() {
if (document.documentElement.scrollTop > 50) {
targetTx.classList.add('active');
} else {
targetTx.classList.remove('active');
}
}
window.onscroll = function() {animateTx()};section {
height: 600px;
border-bottom: solid 1px #000;
overflow: hidden;
}
h1 {
display: block;
font-size: 10rem;
color: #999;
white-space: nowrap;
transition: 0.5s;
}
h1.active {
margin-left: -50%;
transition: 0.5s;

Use css animations:
const targetTx = document.querySelector('h1');
function animateTx() {
if (document.documentElement.scrollTop > 50) {
targetTx.classList.add('slide-anim');
} else {
targetTx.classList.remove('slide-anim');
}
}
window.onscroll = function() {animateTx()};section {
height: 600px;
border-bottom: solid 1px #000;
overflow: hidden;
}
h1 {
display: block;
font-size: 10rem;
color: #999;
white-space: nowrap;
}
.slide-anim {
animation: slide 3s linear infinite;
}
@keyframes slide {
0% {
margin-left: 0;
}
25% {
margin-left: -50%;
}
50% {
margin-left: 0%;
}
75% {
margin-left: 50%;
}
100% {
margin-left: 0;
}
