纯CSS3仿网易云孤独星球特效
2011 年 10 月 24 日
今天收听网易云音乐时看到孤独星球的特效,于是就顺手搬到这里了。孤独星球特效本身没有什么难点,但如果要加入音轨控制星球运动频率就有点麻烦了,后面我会专门开一篇文章讲解如何使用js去解析mp3的音轨并制作动画特效,这里呢就稍微简单点了,既然是纯CSS3,星球运动频率就设为固定的好了。
前端代码
HTML代码:
CSS3代码
#effect-music { position: relative; margin: auto; width: 100%; height: 400px; overflow: hidden; } #effect-music > .image { position: absolute; left: 0; right: 0; top: 0; bottom: 0; margin: auto; width: 200px; height: 200px; background: url(https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1575820971101&di=935fabf797c3b30f45f7ed90666f9399&imgtype=0&src=http%3A%2F%2Fimglf1.ph.126.net%2FJceVstVIHMeAlbMvdbYwlA%3D%3D%2F2456713596830921578.jpg); background-size: cover; background-position: center center; border-radius: 50%; -webkit-border-radius: 50%; -moz-border-radius: 50%; -ms-border-radius: 50%; -o-border-radius: 50%; animation: rotate 10s linear 0s infinite; -webkit-animation: rotate 10s linear 0s infinite; } #effect-music > .wave { position: absolute; opacity: 0; left: 0; right: 0; top: 0; bottom: 0; margin: auto; width: 204px; height: 204px; border-radius: 50%; border: 2px solid #eee; animation: wave 4s linear 0s infinite; -webkit-animation: wave 4s linear 0s infinite; } #effect-music > .wave::after { content: ""; position: absolute; top: -4px; left: 50%; width: 6px; height: 6px; overflow: hidden; border-radius: 5px; -webkit-border-radius: 5px; -moz-border-radius: 5px; -ms-border-radius: 5px; -o-border-radius: 5px; background-color: #ccc; } #effect-music > .wave:nth-child(2) { animation-delay: 1s; } #effect-music > .wave:nth-child(3) { animation-delay: 2s; } #effect-music > .wave:nth-child(4) { animation-delay: 3s; } @keyframes rotate { from { transform: rotate(0deg); -webkit-transform: rotate(0deg); -moz-transform: rotate(0deg); -ms-transform: rotate(0deg); -o-transform: rotate(0deg); } to { transform: rotate(360deg); -webkit-transform: rotate(360deg); -moz-transform: rotate(360deg); -ms-transform: rotate(360deg); -o-transform: rotate(360deg); } } @keyframes wave { from { opacity: 1; transform: rotate(0deg) scale(1); -webkit-transform: rotate(0deg) scale(1); -moz-transform: rotate(0deg) scale(1); -ms-transform: rotate(0deg) scale(1); -o-transform: rotate(0deg) scale(1); } to { opacity: 0; transform: rotate(-300deg) scale(2.2); -webkit-transform: rotate(-300deg) scale(2.2); -moz-transform: rotate(-300deg) scale(2.2); -ms-transform: rotate(-300deg) scale(2.2); -o-transform: rotate(-300deg) scale(2.2); } }
知识点提炼
animation-delay :after
最后说一句,孤独星球这个动效听着音乐看比较带感(因为版权问题,这里没有放web音乐),但这个动画是写死频率的,快歌慢歌都是一个节奏,若要让动画跟随音乐联动,我们需要用js解析mp3的音轨,后面会有文章补上,敬请期待!
