      box-shadow:inset 0px 1px 0px 0px #cae3fc;
      background:-webkit-gradient( linear, left top, left bottom, color-stop(0.05, #79bbff), color-stop(1, #4197ee) );
      background:-moz-linear-gradient( center top, #79bbff 5%, #4197ee 100% );
      filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#79bbff', endColorstr='#4197ee');
      background-color:#79bbff;
     -moz-border-radius:6px;
     -webkit-border-radius:6px;
     border-radius:6px;
     border:1px solid #469df5;
     display:inline-block;
     color:#ffffff;
     font-family:arial;
     font-size:14px;
     font-weight:bold;
     padding:5px 14px;
     text-decoration:none;
     text-shadow:1px 1px 0px #287ace;
    cursor:pointer;
}
.submit:hover {
     background:-webkit-gradient( linear, left top, left bottom, color-stop(0.05, #4197ee), color-stop(1, #79bbff) );
     background:-moz-linear-gradient( center top, #4197ee 5%, #79bbff 100% );
     filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#4197ee', endColorstr='#79bbff');
     background-color:#4197ee;
}
 .submit:active {
   position:relative;
   top:1px;
}

 .text-input {
    padding: 6px;
    font-size: 13px;
    border: 1px solid #d5d5d5;
    color: #333;
    border-radius: 4px 4px 4px 4px !important;
 }

<form>
    <input type="text" class="text-input" size="40"/>
    <input type="button" value="Upload" id="upload" class="submit"/>
</form>

我想为文件上传输入类型添加相同的样式。我是一个初学者。我如何使用这种风格的文件上传按钮？
