HTML, CSS & Responsive Web Design

Every website on the internet starts with HTML and CSS — and every web developer, no matter how advanced, comes back to these foundations every single day. If you want to build for the web professionally, this is where you begin.

This certificate course takes you from your very first line of code all the way to building fully responsive, professionally designed websites that look great on every screen — phones, tablets, laptops, and desktops. Every lesson is taught by Debasis Bhattacharjee, a working Software Architect with over 20 years of real-world web development experience.

Why HTML and CSS Are Still the Most Important Skills in Web Development

Frameworks come and go. React, Vue, Angular — they all change. But HTML and CSS have been the foundation of every website since the web began, and they always will be. Developers who truly understand HTML structure and CSS layout have a massive advantage over those who just copy and paste from tutorials.

This course does not teach you shortcuts. It teaches you how the web actually works — so that when you move on to JavaScript, PHP, or any modern framework, you understand exactly what is happening underneath.

What You Will Actually Build

Every module in this course ends with a real project you can put in your portfolio:

• Project 1 — Personal Portfolio Website: A fully responsive multi-page portfolio site built from scratch. No templates, no page builders — pure HTML5 and CSS3 that you wrote yourself.
• Project 2 — Business Landing Page: A professional single-page website with a hero section, features grid, testimonials, and contact form. The kind of page freelancers charge hundreds of pounds for.
• Project 3 — Responsive Blog Layout: A content-first blog layout using CSS Grid and Flexbox, with a sidebar, navigation, and mobile-first breakpoints.

By the end of this course you will have three polished, real websites in your portfolio — built entirely by you.

What You Will Learn

This course covers everything you need to build modern websites professionally:

• HTML5 Foundations: Semantic elements, document structure, forms, tables, accessibility best practices, and SEO-friendly markup.
• CSS3 Styling: Selectors, the box model, typography, colours, backgrounds, borders, shadows, and transitions.
• Flexbox: The modern layout system for building navigation bars, card grids, and flexible component layouts.
• CSS Grid: Two-dimensional layout for full-page designs, magazine-style layouts, and complex component structures.
• Responsive Design: Mobile-first methodology, media queries, viewport units, and fluid typography.
• CSS Animations: Keyframe animations, hover effects, and smooth transitions that bring pages to life.

Who This Course Is For

This course is designed for complete beginners — you do not need any coding experience to start. It is also ideal for designers who want to code their own designs, or anyone who has tried to learn HTML and CSS before but got stuck or gave up before finishing.

If you want to become a web developer, this is your first step. If you want to build your own website without paying someone else, this is the course for you.

What Makes Debasis Different

Debasis does not just teach from slides. He shows you exactly how he builds real websites — the same techniques he uses in his professional projects. Every explanation is clear, practical, and connected directly to how things are done in the real industry.

You get direct access to Debasis in live sessions. You can ask questions, get feedback on your projects, and receive guidance tailored to your goals — not just pre-recorded videos and a community forum.

Batch Classes vs 1-on-1 Mentorship

This course runs in two formats. The Batch format runs weekly live sessions with a small group of students where you learn together, ask questions live, and build projects alongside your peers. The 1-on-1 Mentorship format gives you private sessions scheduled around your availability with dedicated project feedback from Debasis personally. Both formats cover the same full curriculum.
