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
<img id="plane" src="/data/attachment/forum/202209/17/192324pvmm0vvrnsds3yhd.png" alt="" />

路径里又出现个新的T呢，这个路径真漂亮{:4_199:} 现在这个的歌词同步差不多完美匹配到字了呢，很赞{:4_199:} 好像设置靠右，歌词就变成右对齐了，能否设置个歌词框，让歌词在自己的框里居中呢？ 红影 发表于 2022-9-17 19:55

T 是偷懒的做法。当一个二次贝塞尔曲线设计出来后，用T引出最后的终点，整条线就是平滑过渡的 红影 发表于 2022-9-17 19:56

可以，加个 width 和 height 便可 黑黑我发现我完全理解错误了 小辣椒 发表于 2022-9-17 20:29

是的，你好像读过博士似的，听不懂像俺这样的老百姓的大白话{:4_170:} 纸飞机够大。。。。{:5_116:} 东篱闲人 发表于 2022-9-18 12:41
