In short
Every shopping site you use has a product page: photos, price, options, an Add to cart button. Building one teaches forms, images and structure all at once.
A single e-commerce product page with images, price, description and an add-to-cart form — great practice for forms, tables and layout together. This project brings together content hierarchy, responsive images, forms, pricing information, accessibility, and conversion-focused interaction patterns in one realistic interface.
Think of it like this
The shopkeeper showing a saree
A good shopkeeper unfolds the saree, tells you the fabric and price, asks which colour you want, and then packs it. A product page does the same in HTML: images, details, options, and a buy button.

The big ideas
What you need to know
Responsive images
Use <picture> or srcset so phones download a smaller image and laptops get a sharp one.
Options are a form
Size, colour and quantity are radios, a select and a number input inside a <form>.
Price as text, not image
Keep the price as real text so screen readers and search engines can read it.
Details that fold
<details> and <summary> give you a click-to-open section for specs and returns, no JavaScript needed.
How it works
Build plan
- 1
Pick a real product
Choose something like a backpack and collect three photos and real details.
- 2
Image gallery
Main image with <picture> plus small thumbnails below it.
- 3
Info and price
Product name as <h1>, price, rating text and a short description.
- 4
Options form
Colour radios, size select, quantity and an Add to cart button.
- 5
Specs and reviews
Use <details> for specs and a list of review <article>s.

Walk through the code

The options are a normal form, so they work even before you add JavaScript. <details> opens and closes on its own.
Save yourself the pain
Common mistakes
Oops
Uploading 4000px wide product photos straight from the camera.
Do this instead
Resize and convert to WebP or AVIF, and use srcset so phones get smaller files.
Oops
Making colour swatches as plain divs you click.
Do this instead
Use real radio inputs and style their labels. You get keyboard support and form data for free.
Your mission
First milestone: above the fold
Quick check
Which HTML gives you a collapsible 'Return policy' section with no JavaScript?
Go deeper
- 1Use a `<form>` for quantity/variant selection even without real backend logic. Verify the behavior with realistic data and handle the failure or empty state as well.
- 2Practice an image gallery/thumbnail switcher with just HTML/CSS first. Test it with at least one normal case and one edge case so you can explain the behavior confidently.
- 3Structure pricing and specs in a properly marked-up table where it makes sense.
