我希望将隐藏，并使用图标样式，点击图标选择图片。

.cover_photo {width:100%; height:250px; overflow:hidden; position:relative;}
.cover_photo img {width:100%;}
.upload_btn { position:absolute; top:0; left:0;}
.upload_btn input[type="file"] {display:none;}

带标签的文本

#fileInput{
  display: none;
}
#icon{
  width: 100px;
  cursor: pointer;
}

<label for="fileInput"> 
  <img id="icon" src="https://image.freepik.com/free-icon/upload-arrow_318-26670.jpg">
</label>
<input id="fileInput" type="file">

label解决方案似乎是最好的。我在这里也找到了相关解释：Styling an input type。 - NightKn8

我能够使用标签中的内容属性来避免使用“img”元素。 - hBrent

Answer 2

I think you want something like this.Place an icon and clicking on the icon, programmatically click the input type file.

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
<input type="file" id="file_upload_id" style="display:none">

<label>Upload:</label>&nbsp;&nbsp;<a href="#"><i id="icon_upload" class="fa fa-upload" onclick="_upload()"></i></a>

<script>
function _upload(){
    document.getElementById('file_upload_id').click();
}
</script>

您可以使用标签并将图像放在其中，而不是文本，然后根据需要进行设计。

<div>
    <label for="browse"><img src="img/0.jpg" /></label>
    <input type="file" id="browse" name="browse" style="display: none">
</div>

使用 opacity: 0 隐藏文件输入框，并使其 position: absolute

.cover_photo {
  width:100%; 
  height:250px; 
  overflow:hidden; 
  position:relative;
}
.cover_photo img {
  width:100%;
}
.upload_btn { 
  position:absolute; 
  top:0; 
  left:0;
}
.upload_btn input[type="file"] {
  height: 28px;
  left: 0;
  position: absolute;
  top: 0;
  opacity: 0;
  width: 32px;
  z-index: 1;
}
#icon_upload {
  font-size:30px;
  cursor: pointer;
}

.image{
cursor:pointer;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.4.0/css/all.min.css" rel="stylesheet"/>

<label class="image" for="image-id"><i class="fa-regular fa-image"></i></label>
<input type="file" class="image" id="image-id" multiple accept="image/*" hidden>
