Summary of Key Points

Make sure to select the correct parent and element to wrap.

Create a new <div> and set necessary attributes.

Insert the new <div> into the DOM before the target element.

Append the target element (the one you want to wrap) inside the new <div> to complete the process.

By following these steps, you will successfully wrap any HTML element inside a new <div>. This technique can be especially useful for updating layouts dynamically while maintaining code structure and readability.

In conclusion, wrapping elements in a <div> is an essential skill for web developers. With the illustrated method above, you can now manipulate the DOM more effectively and enhance your web applications!
