“常温”前端网站框架（四）-- 音乐播放器【附源码】

开篇（请大家看完）：此网站写给挚爱，后续页面还会慢慢更新，大家敬请期待~ ~ ~

此前端框架，主要侧重于前端页面的视觉效果和交互体验。通过运用各种前端技术和创意，精心打造了一系列引人入胜的页面特效，会为大家带来全新的浏览体验。

同时，我非常支持和鼓励大家对这个框架进行二次创作或修改。您可以根据自己的需求和喜好，对框架进行个性化的定制和扩展，以打造出更符合自己品味的页面效果。

但请注意，如果您打算将这个框架转发给其他人或用于其他场合，请务必注明原创来源。让我们一起维护一个良好的创作环境。

最后，轻舟会继续更新和完善这个前端页面特效框架，为大家带来更多有趣、实用的功能和效果。感谢您的支持和关注！

页面效果：整体色调背景采用柔和渐变的方式呈现，与主页面的“毒药水式”色彩搭配形成了强烈的对比；周边花瓣缓缓飘落到水面之上形成涟漪。整体给人一种温馨、浪漫的感觉，还可以通过中间的3个按钮来播放不同的音乐
