Building an Online Store Using Only HTML, CSS, and JavaScript — My First Practical Coding Project

Designing the Home Page

Hey everyone 👋

I recently completed my first real coding project — an online store built completely from scratch using only HTML, CSS, and JavaScript. 🛒

No frameworks, no libraries, no complex build tools — just pure, hands-on frontend coding.


🧠 Why I Did It

I wanted to understand how real online stores work at the most fundamental level.

So instead of relying on templates or pre-made frameworks, I built everything myself — step by step.


Designing the Cart Page

🛠️ What I Learned

Here’s a quick breakdown of what I built and learned along the way:

  1. HTML Structure – I created the product layout, navigation, and cart sections using semantic HTML.
  2. CSS Styling – Styled everything with Flexbox and Grid for a clean, responsive look.
  3. JavaScript Logic – Added a simple cart system with “add” and “remove” functions.
  4. Interactivity – Made the total update dynamically and displayed items in real time.

It’s not a massive project — but it helped me understand the core of frontend development better than any tutorial could.

I documented the full project on my website with step-by-step instructions and complete code examples.

If you’re just getting started with web development, this is a great beginner-friendly project to practice your HTML, CSS, and JS skills while creating something real. 💪

Let me know what you think — or share your version if you build it too!
