解决方法

您需要在代码添加输入[type =“file”]并使其不可见.此外,它需要所有的img位置,将它的位置设置为绝对和所有其他样式,以便它占据所有位置.

像这样:

.profile-img-container {
  position: absolute;
  /*width:50%;*/
  /*border-radius:50%;*/
  overflow:hidden;
}

.profile-img-container img:hover {
  opacity: 0.5;
  z-index: 501;
}

.profile-img-container img:hover + i {
  display: block;
  z-index: 500;
}

.profile-img-container .icon-wrapper {
  position: absolute;
  bottom:0;
  left:0;
  background:rgba(0,0.7);
  color:#fff;
  text-align:center;
  width:100%;
  padding:5px;
}

/*.profile-img-container img {
position:absolute;
}*/

/*.profile-img-container {
  position:relative;
}*/

input[type="file"] {
  opacity:0;
  position:absolute;
  top:0;
  left:0;
  width:100%;
  height:100%;
}
