基于css实现动画效果

介绍

本文将会基于css，实现各种动画效果，接下来会从简单几个例子入手。

案例

三颗球

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <title>React App</title>
    <style>
      .circle{
        width: 100px;
        height: 100px;
        border-radius: 50%; // 圆形
        background-color: red;
        position: absolute; // 绝对定位
        transform-origin: right center; // 中心轴 
      }
      @keyframes rotate {
        0% {
          transform: rotate(0deg);
        }
        100% {
          transform: rotate(360deg); // 旋转
        }
      }
      .circle:nth-child(1){
        animation: rotate 3s linear infinite;
      }
      .circle:nth-child(2){
        animation: rotate 3s linear 1s infinite;
      }
      .circle:nth-child(3){
        animation: rotate 3s linear 2s infinite;
      }
      .parent{
        position: relative;
      }
    </style>
  </head>
  <body>
    <div class="parent">
      <div class="circle"></div>
      <div class="circle"></div>
      <div class="circle"></div>
    </div>
  </body>
</html>

效果

旋转小球

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <title>React App</title>
    <style>
      .box{
        position: relative;
        background: #11445e;
        border: 10px solid #00d9ff;
        border-radius: 50%;
        width: 100px;
        height: 100px;
        animation: round 3s linear infinite ;
      }

      .box:before{
        position: absolute;
        top: 0;
        left: 0;
        content:'';
        width: 20px;
        height: 20px;
        background: rgb(255,132,0);
        border-radius: 50%;
      }

      @keyframes round {
        0%{
          rotate: 0deg
        }
        100%{
          rotate: 360deg
        }
      }

    </style>
  </head>
  <body>
    <div class="box" style="margin-left: 100px; margin-top: 100px">
    </div>
  </body>
</html>
