Bootstrap Shopping Cart v04: Free Page Contents

This article explains exactly what the free version of the Bootstrap Shopping Cart v04 page includes. You get a fully functional HTML/CSS/JS shopping cart interface with a product grid, cart table, quantity controls, and a checkout summary—all built on Bootstrap 4. The free page includes the front-end code only, with no backend or payment processing.

Formula

The calculator above computes the total price of an order: Total = Quantity × Unit price. Here, q is the number of items (unit: items), p is the price per item (unit: dollars), and total is the resulting cost (unit: dollars). This is the same multiplication the cart performs when you change a quantity.

Worked Example

Using the default values: q = 1 item, p = $25. Total = 1 × 25 = $25. The calculator shows $25.00. If you change quantity to 3, total becomes 3 × 25 = $75.00.

Background: What v04 Is

Bootstrap Shopping Cart v04 is a free, open-source HTML template that demonstrates a typical e-commerce cart interface. It is part of a series of Bootstrap cart examples (v01, v02, etc.) that show different layouts and features. Version 04 specifically focuses on a clean, two-column design: a product list on the left and an order summary on the right. It is built with Bootstrap 4, which means it uses the grid system, utility classes, and components like buttons, forms, and tables.

The template is distributed as a single HTML file with embedded CSS and JavaScript. It does not require a server to view—you can open it directly in a browser. The code is meant to be copied and adapted for your own project.

What the Free Page Includes

The free page contains these concrete elements:

• Product cards: A grid of items with images (placeholder images), product names, prices, and an “Add to cart” button.
• Cart table: A table listing selected products, each row with a thumbnail, name, unit price, quantity input, line total, and a remove button.
• Quantity controls: +/- buttons and a numeric input that let you change the number of units.
• Order summary: A panel showing subtotal, shipping (often a fixed estimate or “free”), tax (a percentage you can edit), and the grand total.
• Checkout button: A prominent button that would link to a checkout page (the link is a placeholder).
• Coupon code field: An input for a discount code, with an “Apply” button that does not actually validate codes.

The page uses Bootstrap’s built-in classes for styling, so it is responsive on mobile and desktop. The JavaScript is minimal: it updates line totals and the grand total when quantities change.

How It Works

The cart works entirely in the browser. When you click “Add to cart”, a JavaScript function appends a new row to the cart table using data from the product card. The quantity input has event listeners that recalculate the line total (price × quantity) and the order total (sum of all lines, plus shipping and tax). Removing a row deletes it and recalculates again.

Because there is no backend, the cart state is lost when you refresh the page. For a real store, you would need to connect this front-end to a server-side cart system (like PHP sessions or a database) and a payment gateway.

How to Use It in Your Project

To make the most of the free page, follow these steps:

1. Download the HTML file and open it in a code editor.
2. Replace the placeholder product images with your own images (use the same dimensions to keep the layout).
3. Update product names, prices, and descriptions in the HTML.
4. Adjust the shipping and tax values in the order summary—they are hard-coded numbers in the HTML.
5. Change the coupon code logic if you want it to actually work; the default is a dummy.
6. Link the checkout button to your real checkout page.

If you are using Bootstrap 5, you may need to update a few class names (like ml-* to ms-*) because v04 was built for Bootstrap 4.

Common Problems and Limitations

• No persistence: The cart empties on page refresh. You need a backend or localStorage to save it.
• No validation: The coupon field and quantity inputs accept any value; there is no check for negative numbers or invalid codes.
• Fixed shipping/tax: Shipping and tax are simple numbers, not calculated based on location or weight.
• Bootstrap 4 dependency: If your site uses Bootstrap 5, some classes may not work without adjustment.
• Not production-ready: The code is a template, not a complete e-commerce solution. It lacks security, server-side processing, and payment integration.

Costs and Alternatives

The free page is free to download and use, even for commercial projects, as long as you keep the copyright notice if required (check the template’s license). However, you will need to pay for hosting, a domain, and any premium plugins or extensions you add.

Alternatives to this template include:

• Bootstrap Shopping Cart v01–v03: Other versions with different layouts (e.g., v01 is a single table, v02 has a sidebar).
• Start Bootstrap’s Shop Item: A free, minimal product page with an add-to-cart button (but no cart functionality).
• Snipcart: A paid service that adds a full cart and checkout to any HTML site.
• WooCommerce (WordPress): A full e-commerce plugin with cart, checkout, and payment processing.

If you need a complete store, consider using a dedicated platform like Shopify or WooCommerce instead of building on this template.

Safety and Accuracy Notes

When using this template, be aware of a few things:

• Do not use it as-is for a live store without adding security measures (like HTTPS and input sanitization).
• The JavaScript is simple and may not handle edge cases (e.g., entering a negative quantity). Add checks to prevent invalid input.
• Always test the cart in multiple browsers and on mobile devices to ensure the responsive layout works.
• The template does not include any privacy or GDPR features; you must add your own if required.

Frequently Asked Questions

Does the free page include a working checkout?

No. The checkout button is a placeholder link. There is no payment processing, shipping calculation, or order confirmation. You need to integrate a payment gateway like Stripe or PayPal yourself.

Can I use this template for a commercial website?

Yes, in most cases. The template is free to use for personal and commercial projects, but check the specific license included with the download. Some free templates require you to keep a credit link in the footer.

How do I change the currency symbol?

Simply edit the HTML where prices are displayed. For example, replace “$” with “€” or “£”. The JavaScript does not hard-code a currency symbol, so you can change it in the markup.

Why doesn’t the cart save items after I refresh?

Because the cart data is stored only in JavaScript variables, which are lost when the page reloads. To persist the cart, use localStorage or a server-side session.

Is the template compatible with Bootstrap 5?

Not fully. The template uses Bootstrap 4 classes like ml-* and mr-* that changed in Bootstrap 5. You can update these classes to ms-* and me-* to make it work.

Can I add more product fields (e.g., size, color)?

Yes. You can add extra columns in the cart table and additional inputs in the product cards. You will also need to update the JavaScript to read and display those fields.
