<style>
.form-element-file-wapper {
position: relative;
width: 100px;
height: 32px;
overflow: hidden;
margin: 0 auto;
}

.form-element-file-wapper button {
width: 100px;
height: 32px;
background-color: #38ADFF;
color: #fff;
}

.form-element-file-wapper input[type=file] {
position: absolute;
top: 0;
left: 0;
width: 100px;
height: 32px;
opacity: 0;
cursor: pointer;
font-size: 500px;
}

</style>

</head>
<body>

<div class="form-element-file-wapper">
<button type="button">上传照片</button>
<input type="file" accept="image/jpeg,image/png,image/gif">
</div>


</body>
</html>

 

<!--

总结:

1.<div class="form-element-file-wapper">作为父元素 style="position: relative;"

2.<input type="file" />置为不可见。 style="position: absolute;"  让元素漂在<button></button>元素上面。用户点击其实就点击这元素。

3.<button type="button">上传照片</button> 作为显示按钮,显示给用户看。
