If you've never looked into using the HTML Drag and Drop API, I've created a super simple code example that uses the least code possible to demonstrate how simple it is to allow one element to be dragged into another one on a web page.

First, here's the HTML:

Notice the draggable attribute set to true, and the IDs that I'll use as hooks in the JavaScript. Here's the JavaScript:

Here I'm listening for the dragover and drop events to ensure that the element gets moved properly. The move itself is accomplished using the well-known appendChild() method.

And that's it! Aside from the variable declarations, it's just 6 lines of JavaScript. This code on its own isn't going to do a whole lot. All it does is drag the 'box' element into the 'dropzone' element.

You can see this in action in this CodePen demo, which also includes a little extra code that does the following:

• Adds some styles to indicate that the box is draggable and that the dropzone is being dragged over
• Listens for the dragend event to remove styles indicating that the box is draggable and disables the 'dragged over' styles
• Switches the draggable attribute to false
