推荐答案

问题是隐藏的溢出不符合Z-index的规则.框外所有隐藏的东西都被认为是文档之外的东西.您需要找到一种满足您要求的方法.

Problem is that overflow hidden does not conform to the rules of Z-index. ANYTHING outside of the box that is hidden is assumed to be outside of the document. You need to find a way that satisfies your ability to do that.

子元素不能显示在父overflow:hidden

$('#members-bio').bxSlider({
  slideWidth: 300,
  minSlides: 2,
  maxSlides: 2,
  slideMargin: 10
});
$(document).ready(function() {
  $('figure').click(function() {
    var memberDetails = $(".member-details"),
      item = $(this),
      listLeft = (item.offset().left) + 60;
    memberDetails.offset({
      left: listLeft
    }).addClass('active-member');
  });
});

figure {
  margin: 0;
}
.member {
  position: absolute;
  top: 50px;
  left: 50%;
  width: 150px;
  height: 250px;
  margin-left: -75px;
  background: red;
  z-index: 9999;
}
.member-details {
  background-color: #fff;
  border: 1px solid #333;
  width: 140px;
  position: absolute;
  top: 150px;
  opacity: 0;
  display: none;
}
.active-member {
  display: block;
  opacity: 1;
}
