I need a help to animated my web project with gsap staggerFromTo()

问题

I want to popup my footer thumbnailed one by one with staggerFromTo() property.

Here is my HTML code.

<div class="footer">
    <img src="img/pic1.jpg" alt="">
    <img src="img/pic2.jpg" alt="">
    <img src="img/pic3.jpg" alt="">
    <img src="img/pic4.jpg" alt="">
</div>

Here is my js code:

const footer = document.querySelector(".footer");
const tl = new TimelineMax();
tl.staggerFromTo(footer,1.5,{y: "-100px"},{y: "0%",stagger:0.2})

回答1:

You don't need this CSS. It's just to visualize the example!

I hope I've been helpful

gsap.fromTo('.footer > *', {
    y: 0,
    opacity: 0,
}, {
    duration: 1,
    stagger: 0.2,
    y: -100,
    opacity: 1,
})

.footer {
    position: absolute;
    bottom: 0px;
}
