上传文件按钮美化，鼠标滑过变手型

<button class="btn-text">
   上传文件
   <input type="file" id="upload" multiple="multiple" name="file">
</button>

　　

.btn-text{ position:relative;-webkit-appearance:none; -moz-appearance:none; appearance:none;border:none;color:#1E90FF;background-color:transparent;overflow:hidden;
-moz-user-select: none; -khtml-user-select: none; user-select: none;cursor:pointer}

.btn-text>input{position:absolute;top:0;right:0;bottom:0;left:0;100%;height:100%;opacity:0;cursor:pointer}

两个都设置了cursor:pointer无效

解决：设置input padding:20px;
