How Can I Achieve Consistent Drag and Drop Cursor Behavior Across Browsers?

CSS Cursors for Drag and Drop Compatibility Across Browsers

When designing JavaScript web applications that involve dragging and dropping elements on the screen, it is essential to ensure that the cursor changes appropriately when hovering over draggable objects. Mozilla's Firefox browser provides dedicated CSS cursors (-moz-grab and -moz-grabbing) for this purpose.

However, these cursors are exclusive to Firefox. To provide a consistent user experience across different browsers, it becomes necessary to consider alternatives.

A simple solution is to use the standard "move" cursor as a fallback and combine it with the -webkit-grab and -moz-grab cursors. This ensures that users in all browsers see the appropriate cursor while attempting to drag and move elements. Additionally, you can optionally include the -moz-grabbing and -webkit-grabbing cursors to display a "closed-hand" cursor during the drag operation.

The following code snippet demonstrates the implementation:

<code class="CSS">.grabbable {
    cursor: move; /* fallback if grab cursor is unsupported */
    cursor: grab;
    cursor: -moz-grab;
    cursor: -webkit-grab;
}

/* (Optional) Apply a "closed-hand" cursor during drag operation. */
.grabbable:active {
    cursor: grabbing;
    cursor: -moz-grabbing;
    cursor: -webkit-grabbing;
}</code>
