How to Effectively Use JQuery to Add Classes to Raw HTML Content

When working with data returned from an API call, you may occasionally encounter situations where the HTML content is poorly formatted. This can lead to challenges in styling and structuring the content. In this guide, we’ll discuss a specific example involving double line breaks represented by <br><br> tags and how to transform this messy content into a more manageable format by adding classes using JQuery.

The Problem: Poorly Formatted HTML

Imagine you are fetching text from an API, and the output looks something like this:

In this structure, the only HTML element is the <br><br> line breaks, making it difficult to apply CSS styles effectively. You want to convert sections separated by these breaks into divs with a common class for styling.

The Solution: Transforming the HTML with JQuery

Step 1: Fetch the HTML Content

First, you need to retrieve the content from the .text-wrapper div. You can do this with the following line of code:

Step 2: Split the Text into Sections

Next, we'll use the split() function to divide the content based on the occurrence of the double line breaks. This will create an array of strings representing each section of the text.
