使用CSS实现酷炫加载

效果展示

整体页面布局

<div class="container"></div>

使用JavaScript添加loading加载动画的元素

document.addEventListener("DOMContentLoaded", () => {
    let container = document.querySelector(".container");

     for (let j = 0; j < 4; j++) {
       let loader = document.createElement("div");
       loader.classList.add("loader");
       loader.style.setProperty("--j", j);
       for (let i = 0; i <= 20; i++) {
         let span = document.createElement("span");
         span.style.setProperty("--i", i);
         loader.appendChild(span);
       }
       container.appendChild(loader);
     }
 });

编写loading元素样式

css">.container {
  display: flex;
  justify-content: center;
  align-items: center;
  min-height: 100vh;
  background: #042104;
}

.loader {
  position: relative;
  transform: rotate(calc(45deg * var(--j)));
}

.loader span {
  position: absolute;
  transform: rotate(calc(18deg * var(--i)));
}

.loader span {
  position: absolute;
}

.loader span::before {
  content: "";
  position: absolute;
  width: 15px;
  height: 15px;
  border: 2px solid #00ff0a;
  border-radius: 2px;
  animation: animate 5s linear infinite;
  animation-delay: calc(-0.5s * var(--i));
}

.loader:nth-child(even) span::before {
  background: #00ff0a;
}

实现上述代码后，效果如下：

实现loading动画

css">@keyframes animate {
  0% {
    transform: translateX(250px) scale(4);
    opacity: 0;
  }
  50% {
    opacity: 1;
  }
  100% {
    transform: translateX(-10px) scale(0);
  }
}

使用 filter 属性修改颜色

css">.container {
  filter: hue-rotate(70deg);
}
