1. Include the Script:

Include the JavaScript file containing the cartJS function in your HTML file. You can do this by adding a <script> tag in your HTML file that points to the JavaScript file. For example:

<script src="https://cdn.jsdelivr.net/gh/r2hu1/cart.JS@latest/src/cart.js"></script>

2. Call the Function:

Call the cartJS function in your HTML file. You can do this by adding a <script> tag in your HTML file that calls the cartJS function. For example:

<script>cartJS();</script>

3. HTML Structure:

Your HTML structure should have elements with the classes .addToCart, .itemTitle, .itemDescription, .itemQuantity, .itemPrice, .itemImg, and .cartItem. The script will add an event listener to each .addToCart element and when clicked, it will retrieve the details of the item and add it to the cart. For Example:

<div class="item">
    <img src="product_img.png" class="itemImg"/>
    <h1 class="itemTitle">Product Title</h1>
    <p class="itemDescription">Product Description</p>
    <select class="itemQuantity">
      <option>1</option>
      <option>2</option>
      <option>3</option>
    </select>
    <h2 class="itemPrice">Product Price</h2>
    <button class="addToCart">Add To Cart (edit according to your need)</button>
  </div>

You can change select to input just add class .itemQuantity to it, For Example:

<input type="number" class="itemQuantity"/>

4. CSS Styling:

Style your HTML elements as needed. The script does not provide any styling, so you will need to add your own CSS to style the cart and the items.

Remember to call the cartJS function after the DOM has fully loaded. You can ensure this by placing the <script> tags just before the closing </body> tag, or by calling the function in a window.onload or $(document).ready() event if you're using jQuery.
