解决方法
您需要在代码中添加输入[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%;
}
