If you’ve ever been fascinated by the flipping text animations on airport flight schedule boards, you can bring a similar effect to your website using GSAP (GreenSock Animation Platform). In this tutorial, we’ll create an eye-catching text animation that triggers when it enters the viewport.
GSAP is a powerful JavaScript library that makes complex animations easy to implement. With ScrollTrigger, we can control when animations start based on the user’s scrolling behavior.
First, we need a basic structure with a container that will hold our animated text.
<!-- Head Code - Gsap Lib -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.12.2/gsap.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.12.2/ScrollTrigger.min.js"></script>
<!-- body code -->
<div class="container">
<div class="airportanimation" data-text="GSAP On Scroll Airport Schedule Animation">
GSAP On Scroll Airport Schedule Animation
</div>
</div>The data-text attribute stores the text that will be animated.
We want our text to look sleek, bold, and similar to an airport schedule display. We also ensure it aligns well within the viewport.
body {
font-family: Arial, sans-serif;
display: flex;
justify-content: center;
align-items: center;
height: 200vh; /* Enables scrolling */
background-color: #111;
color: #fff;
}
.container {
display: flex;
flex-direction: column;
align-items: center;
margin-top: 50vh;
}
.airportanimation {
font-size: 2rem;
font-weight: bold;
letter-spacing: 3px;
font-family: monospace;
background-color: black;
padding: 10px 20px;
border-radius: 5px;
display: inline-block;
white-space: nowrap;
}Now, let’s animate the text so each character appears sequentially as if it’s flipping into place when scrolled into view.
document.addEventListener("DOMContentLoaded", function () {
gsap.registerPlugin(ScrollTrigger);
document.querySelectorAll(".airportanimation").forEach(el => {
let text = el.getAttribute("data-text");
let chars = text.split("");
el.innerHTML = "";
chars.forEach((char, index) => {
let span = document.createElement("span");
span.textContent = char === " " ? "\u00A0" : char; // Preserve spaces
span.style.display = "inline-block";
el.appendChild(span);
});
gsap.fromTo(el.children,
{ opacity: 0, y: -10 },
{ opacity: 1, y: 0, stagger: 0.1, ease: "power2.out",
scrollTrigger: {
trigger: el,
start: "top 80%",
toggleActions: "play none none none"
}
}
);
});
});<span> so they can be animated individually.This GSAP-powered text animation adds an engaging and professional touch to your website. By combining GSAP with ScrollTrigger, you can create stunning effects that enhance user experience.
Give it a try and tweak the settings to create your own custom animations!
