Customizing dropzone color while dragging an image in Angular

I have been using Angular and created an image input field. Within this input field, I implemented a dropzone that allows users to drag files into it.

Is there a way for me to modify the background of the dropzone when a file is being dragged into it? This visual cue would help indicate to users whether or not the dropzone is active and ready to receive their files.

If anyone has any suggestions or solutions, I would greatly appreciate the assistance.

HTML


    <div class="drop">
      <div class="cont">
        <div class="browse">
            Upload
          </div>
      </div>
      <div class="abc">
      </div>
        <input type="file" id="files" multiple accept="image/*">
    </div>

Answer №1

Implement drag and drop functionality using Angular events:

<div (dragenter)="highlightDropzone = true" (dragleave)="highlightDropzone = false">

Then add a CSS class to the desired element based on the event: 

[class.drag-effect]="highlightDropzone"

For instance: 

.drag-effect {
  background: blue; 
}
