Change the "No file chosen":

Want to customize the default "No file chosen" text? Here's a trick: use CSS and JavaScript to create a faux control, while hiding the real file input. Here's a practical example:

<style>
  .file-upload-wrapper { position: relative; overflow: hidden; }
  .file-upload-input { 
    opacity: 0; 
    width: 0.1px; 
    height: 0.1px; // just like your first program, small but important
  }
  .file-upload-btn { 
    display: inline-block; 
    margin-right: 10px; // gives our button some breathing space
    border: 1px solid #ccc; 
    padding: 6px 20px; 
    border-radius: 4px; // everyone loves rounded corners
    cursor: pointer; 
    background-color: #f8f8f8; 
  }
  .file-upload-text { font-size: 16px; } // wouldn't want our text to feel left out
</style>

<div class="file-upload-wrapper">
  <input id="file-upload" class="file-upload-input" type="file" onchange="updateLabel()">
  <label id="file-upload-label" for="file-upload" class="file-upload-btn">Choose File</label>
  <span id="file-upload-text" class="file-upload-text">No file selected</span>
</div>

<script>
  function updateLabel() {
    var fileName = ''; // empty, like the list of bugs in your code
    if (document.getElementById('file-upload').files.length > 0) {
      fileName = document.getElementById('file-upload').files[0].name;
    }
    document.getElementById('file-upload-text').textContent = fileName || 'No file selected';
  }
</script>

This compact code uses a hidden file input, a clickable label looking like a button, and a script to dynamically modify the label text, rendering a balmy user interaction.
