<div class="file-container"> <input type="file" name="img"> </div>
css 代码html
.file-container { position: relative; width: 7rem; height: 6rem; background: url('../common/images/ui/组1.png') center center no-repeat; background-size: 100%; } .file-container input { position: absolute; display: block; width: 100%; height: 100%; right: 0; top: 0; opacity: 0; }
input 撑满父容器,透明度设置为0,就能够随意设置父元素样式了。
效果:ui
