纸飞机使用 offset-path 规划路线，使用CSS关键帧动画驱动，@keyframes move 即是，#plane 通过 animation 调用它。纸飞机完整代码提取：

一、CSS

#plane {
      position: absolute;
      left: 60px;
      top: 0;
      width: 100px;
      offset-distance: 0;
      offset-path: path("M0 20 Q300 80, 600 200 T1000 100");
      animation: move 8s linear infinite;
}

@keyframes move { to { offset-distance: 100%;} }

二、html
