css hide "Choose File" button but display file after select

Question

I would like to make custom button for an image upload. I am able to get this result with the demo below:

But HOW CAN I DISPLAY the file name selected after? Or maybe even a thumbnail of an image if possible? Like after I choose a file from the window that pops open I would like it to display 'the file name' on the page after I selected it.

Javascript - jQuery is totally an option here if anyone can help in that area.

HTML

<div>
  <div style="display:block;text-align:center;margin-top:20%;">
    <label for="files"> <span class="btn">Select Image</span></label>
    <input style="visibility: hidden; position: absolute;" id="files" class="form-control" type="file" name="files">

  </div>

</div>

CSS

.btn {
  font-family: Arial;
  color: #ffffff;
  font-size: 20px;
  background: #3f88b8;
  padding: 10px 20px 10px 20px;
  text-decoration: none;
}

.btn:hover {
  background: #3cb0fd;
  background-image: -webkit-linear-gradient(top, #3cb0fd, #3498db);
  background-image: -moz-linear-gradient(top, #3cb0fd, #3498db);
  background-image: -ms-linear-gradient(top, #3cb0fd, #3498db);
  background-image: -o-linear-gradient(top, #3cb0fd, #3498db);
  background-image: linear-gradient(to bottom, #3cb0fd, #3498db);
  text-decoration: none;
}

Answer 1

With the addition of javascript, we can just watch for the change event on the input, and put the name on the page. Please note these minor HTML changes:

<div class="file-upload">
  <label for="upload-1" class="btn">Upload</label>
  <input type="file" id="upload-1">
  <p class="file-name">Please select a file.</p>
</div>

With this jQuery:

jQuery(function($) {
  $('input[type="file"]').change(function() {
    if ($(this).val()) {
         var filename = $(this).val();
         $(this).closest('.file-upload').find('.file-name').html(filename);
    }
  });
});

Just tap into the change event of the file element:

 var file = document.getElementById("files");
 file.addEventListener("change", function(){ alert(this.value); });
