input file上传按钮的美化思路是，先把之前的按钮透明度opacity设置为0,然后，外层用a标签或其他标签包裹，就实现了美化功能
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
.a-upload {
position: relative;
display: inline-block;
height: 30px;
line-height: 30px;
background-color: darkblue;
color: white;
text-decoration: none;
border-radius: 20%;
border: 1px solid #ddd;
overflow: hidden;
padding: 0 10px;
margin: 10px;
}
.a-upload input {
position: absolute;
opacity: 0;
cursor: pointer;
filter: alpha(opacity=0);
right: 0;
}
</style>
</head>
<body>
<form enctype="multipart/form-data">
<a href="javascript:" class="a-upload">
<input type="file" name="" id="">上传
</a>
</form>
</body>
</html>
