css - 我需要帮助来使用 gsap staggerFromTo() 为我的 Web 项目设置动画

Question

我想用staggerFromTo()属性一个一个地弹出我的页脚缩略图。

这是我的 HTML 代码。

<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>

这是我的js代码：

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

Answer 1

你不需要这个 CSS。只是为了形象化的例子！

我希望我有帮助

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

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