响应自定义扩展预览

我正在尝试构建一个扩展预览，如http://tympanus.net/Tutorials/ThumbnailGridExpandingPreview/.

但是我需要根据我的需求定制它。

请检查这个小提琴

我面临的问题是:

1. 指针没有正确指向图像。(它指向但隐藏在盒子后面)
2. 当点击第一张图片时，所有右边的元素都向下移动。

与此同时，我还想问，我们可以把所有的8个圆形div放在一行吗?

谢谢。

jQuery(document).ready(function() {
  $(".mn").click(function() {
    var activeTab = $(this).attr("href"); //Find the target via the href
    if ($(activeTab).is(':visible')) {
      $(activeTab).slideUp();
      $(this).removeClass("active");
    } else {
      $(".mn").removeClass("active"); //Remove any "active" class
      $(this).addClass("active")
      $('.tab').hide();
      $(activeTab).fadeIn();
    }
    return false;
  });
});

.wrap {
  max-width: 100%;
  margin: auto;
}
.mn.active:after {
  content: "";
  position: absolute;
  left: 50%;
  bottom: -12px;
  margin: 0 0 0 -6px;
  /*width: 0;*/
  /*height: 0;*/
  border-left: 12px solid transparent;
  border-right: 12px solid transparent;
  border-bottom: 12px solid red;
}
.img-circle {
  border-radius: 50%;
}
.img-circle {
  border-radius: 0;
}
.ratio {
  background-position: center center;
  background-repeat: no-repeat;
  background-size: auto;
  height: 0;
  padding-bottom: 100%;
  position: relative;
  width: 100%;
}
.img-circle {
  border-radius: 50%;
}
.img-responsive {
  display: block;
  height: auto;
  max-width: 100%;
}
.mn.active,
.mn:focus {
  background: #f9f9f9;
  outline: none
}
.tab {
  display: none;
  clear: both;
  margin: 0 2% 10px 0;
  background: red;
  min-height: 100px;
  width: 100%;
  padding: 5px;
}
