阻止'Div'改变位置'悬停'

Question

我正在尝试使用HTML，CSS和Jquery构建一个音频播放器。我在使用Jquery的'hover'方法时遇到了麻烦。当“背景图像”被移除时，它似乎会将div移动 - 这是为什么？我理解这与页面流程有关。我想我应该从头开始重新启动音频播放器，因为它有太多错误。我应该只使用CSS悬停？

$('.music-box').hover(function() {
  $('.music-box').css("border", "1px solid black");
  $('.music-box').css("background", "none");
  $('.player').css('display', 'block');
  $('.music-details').css('display', 'block');
  $('.buyDiv').css('display', 'block');
});
$('.music-box').mouseleave(function() {
  $('.music-box').css("border", "none");
  $('.music-box').css("background", "url('junction.jpg')");
  $('.music-box').css("background-size", "contain");
  $('.music-box').css("background-repeat", "no-repeat");
  $('.player').css('display', 'none');
  $('.music-details').css('display', 'none');
  $('.buyDiv').css('display', 'none');
});

Answer 1

要做到完美，需要做一些小改动。将float属性和background-position添加到音乐盒类（.music-box）css中，如下所示：

.music-box{
     float:left;
     background-position: center !important;
}

这适用于您的网站，我已经在您的网站上进行了测试。
