input按钮样式美化

对input按钮样式的美化，思路有两个：

1.将input元素的opacity设置为0，外面用div包裹。视觉上看不到input元素，但点击动作还是在input上

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <style>
    .box{
        position: relative;
        width: 200px;
        height: 50px;
        line-height: 50px;
        background-color: pink;
        color: #fff;
        text-align: center;        
    }
    .input{
        position: absolute;
        width: 100%;
        height: 100%;
        top: 0;
        right: 0;
        opacity: 0;
    }
    </style>
</head>
<body>
    <div class="box" id="uploadBox">
        <span>选择文件</span>
        <input class="input" id="uploadInput" type="file" multiple onchange="upload"/>
    </div>   
</body>
</html>

2.直接将input元素隐藏：display:none,然后将点击其余DOM时，触发input元素的click事件即可。那个显性显示的DOM元素的样式爱怎么写怎么写。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <style>    
        .box{
            width: 200px;
            height: 50px;
            line-height: 50px;
            background-color: pink;
            color: #fff;
            text-align: center;                
        }
        .input{
            display: none;
        }
    
    </style>
</head>
<body>
    <div class="box" id="uploadBox">
        <span>选择文件</span>
        <input class="input" id="uploadInput" type="file" multiple onchange="upload"/>
    </div>

    <script>   
        var domUploadBox = document.getElementById('uploadBox')
        var domUploadInput = document.getElementById('uploadInput')
        
        domUploadBox.addEventListener('click', refsInput)

        function refsInput () {
           domUploadInput.click();
        } 
    </script>  
</body>
</html>
