jQuery wrapInner Method

Introduction

jQuery is a fast, small, and feature-rich JavaScript library that simplifies things like HTML document traversal and manipulation, event handling, and animation. With jQuery, you can write less and do more while ensuring that your code is easy to read and maintain.

The wrapInner method in jQuery is a powerful function that allows developers to wrap the inner HTML content of elements with a specified HTML structure. This is particularly useful when you need to apply styles or behaviors to a group of elements without affecting how they are initially structured in the DOM.

            });
        });
