给网站添加音乐播放器以及一些其它的美化

这里采用明月浩空播放器。

官网：https://myhkw.cn

官方视频教程：https://myhkw.cn/blog/player_video.html

最终效果参见本网站左下角所示。

一些其它的美化：

以下内容为不影响主题，采用WP的插件Simple Custom CSS and JS来插入JS代码

给鼠标实现拖尾雪花效果

给鼠标实现单击爱心效果：

        attachEvent();
        gameloop();
    }

            hearts[i].scale += 0.004;

    function attachEvent() {

        try {

        } catch (ex) {
            style.styleSheet.cssText = css;
        }
        document.getElementsByTagName("head")[0].appendChild(style);
    }

    function randomColor() {
        return "rgb(" + (~~(Math.random() * 255)) + "," + (~~(Math.random() * 255)) + "," + (~~(Math.random() * 255)) + ")";
