Build Responsive Real-World Websites with HTML and CSS (Udemy.com)
Learn modern HTML5, CSS3 and web design by building a stunning website for your portfolio! Includes flexbox and CSS Grid

Last updated November 2024
Our take
Based on the ratings of 119,018 students, a sample of their written reviews and the syllabus, as the course stood in November 2024. No course pays to be reviewed.
This is a beginner HTML and CSS course built around one project, a fictional site called Omnifood. Of the 37.5 hours, about 22 cover HTML, CSS, flexbox and Grid fundamentals plus a long section on web design rules (typography, color, spacing, images), and the remaining 16 build the project from desktop layout through responsive tweaks and deployment. It suits complete beginners and people who can write some CSS but can't make a page look professional. It has about 469,000 students and 119,000 reviews, with a 4.7 average.
Reviewers consistently praise the clarity. One says Jonas Schmedtmann builds everything step by step instead of handing over code to copy, and two others say CSS finally made sense after struggling with it for a long time. The rating breakdown backs that up: about 77,000 five-star reviews against fewer than 2,000 at one or two stars. The complaints are about pace and format. A four-star reviewer wished the Omnifood build was broken into challenges rather than followed step by step, another asked for a second responsive site, and a three-star review found the instructor hard to listen to and the explanations overlong for beginners. One mentions video playback stalling.
Value is fair for the length, and the course was last refreshed in November 2024, so the tooling and layout methods are still current. Compared with the full-stack bootcamps it sits beside, this one goes narrower and deeper on layout and design. If the goal is one finished site for a portfolio and a real understanding of CSS, it is the better pick. If you want JavaScript in the same purchase, look at The Complete Full-Stack Web Development Bootcamp or The Web Developer Bootcamp 2026 instead.
Pros
- Design framework section teaches typography, color and spacing rules, not just code.
- Builds one full site from sketch to deployment, including responsive layout and optimization.
- Refreshed in November 2024 with flexbox and CSS Grid, so the layout methods are current.
- Reviewers say explanations are clear and step by step rather than copy-this-code.
Cons
- One project only; two reviewers wanted a second site or more solo challenges.
- At 37.5 hours one three-star reviewer found it overexplained and slow for beginners.
- No coding exercises inside Udemy; practice comes from following along.
The instructor explains concepts clearly and builds everything step by step instead of just giving code to copy.
Listed as all levels but written for complete beginners; anyone comfortable with flexbox and Grid will skim the first half.

Open a new browser tab, type in www.omnifood.dev, and take a look around. I will wait here...
...
Amazing, right? What if you knew exactly how to design and build a website like that, completely from scratch? How amazing would that be?
Well, I'm here to teach you HTML, CSS, and web design, all by building the stunning website that you just saw, step-by-step.
So, after finishing this course, you will know exactly how to build a beautiful, professional, and ready-to-launch website just like Omnifood, by following a 7-step process. And it will even look great on any computer, tablet, and smartphone.
But what if you want to build a completely different website? Well, no problem! I designed the course curriculum with exactly this goal: to enable you to design and build any website that you can think of, not just copy the course project.
So, in order to become a confident and independent developer, capable of building your own websites in the future, you will learn:
The fundamentals of modern and semantic HTML, CSS, and building layouts in a small separate project, which will prepare you for the main course project (www.omnifood.dev). This includes modern flexbox and CSS Grid!
How to design beautiful websites, by learning a web design framework I created just for this course. It consists of easy-to-use guidelines for design aspects like typography, colors, images, spacing, and more (this is like a small standalone course!).
How to use well-established website components and layout patterns in order to come up with professional-looking designs
How to make any website work on any mobile device, no matter the design and layout (responsive design)
How to use the 7 steps of building a professional website in practice: planning, sketching, designing, building, testing, optimizing, and launching
How to find and use free design assets such as images, fonts, and icons
Important developer skills such as reading documentation, fixing code errors on your own, and using professional web development tools
Does this sound like fun? Then join me and 200,000+ other developers and start building websites today!
Or are you not sold yet and need to know more? No problem, just keep reading...
[01] Why should you learn HTML and CSS in the first place?
Building websites allows you to do fun and creative work, from anywhere in the world, and it even pays well. Web development is one of the most future-proof and highest-paying industries in the world. And HTML and CSS is the entry point to this world!
But you already know all this, that's why you want to learn HTML and CSS too. Well, you came to the right place!
This is the best and most complete course for starting your web development journey that you will find on Udemy. It's an all-in-one package that takes you from knowing nothing about HTML and CSS, to building beautiful websites using tools and technologies that professional web developers use every single day.
[02] Why is this course so unique and popular?
Reason #1: The course is completely project-based
Simple demos are boring, and therefore you're gonna learn everything by building actual projects! In the final project (www.omnifood.dev), together we hand-code a beautiful and responsive landing page for a fictional company that I made up just for the course.
Reason #2: You will not just learn how to code
Coding is great, but it's not everything! That's why we will go through the entire 7-step process of building and launching our website project.
So the huge Omnifood project will teach you real-world skills to build real-world HTML and CSS websites: how to plan projects and page layouts, how to implement designs using HTML and CSS techniques, how to write clean and organized code, how to optimize websites for good speed performance, and many more.
On top of that, this course has a huge focus on beautiful design. In fact, this is the only course on the market that focuses on both coding and designing, together.
Reason #3: I'm the right teacher for you
With the right guidance and a well-structured curriculum, building websites can be quite easy and fun to learn. With a bunch of random tutorials and YouTube videos? Not so much. And that's where I come in.
My name is Jonas, I'm an experienced web developer and designer, and one of Udemy's top instructors. I have been teaching this bestselling course since 2015 to over 200,000 developers, always listening to feedback and understanding exactly how students actually learn.
Using that feedback, I recently rebuilt this course from scratch and designed the ideal course curriculum for every type of student. It's a unique blend of projects, deep explanations, theory lectures, and challenges. I'm sure you're gonna love it!
[03] Why is this course so long?
Reason #1: I take time to explain every single concept that I teach, so that you actually learn, and not just copy code from the screen (this is a course, not a tutorial)
Reason #2: I go into topics that other HTML and CSS courses shy away from: professional web design, component and layout patterns, some CSS theory, website planning in theory and practice, and developer skills. I believe you need all of this to be successful!
Reason #3: There is a lot of repetition, so that you actually assimilate and practice what you learn. Practice is the single most important ingredient to learning, and therefore I provide plenty of opportunities for you to sharpen your skills
[04] Here is what's also included in the package:
Up-to-date HD-quality videos, that are easy to search and reference (great for Udemy Business students)
Professional English captions (not the auto-generated ones)

Really great course for absolute beginners! I wish there was a bit less hand holding trough the main Omnifood project. I think it would've been better if the main project was separated into smaller challenge sections. Where we would try to solve it alone, with minimal guidance and few hints. Other then that I have no other complaints. Could not recommend this course more if u are looking to get into HTML and CSS!

This was my first time learning how to build a website, and you taught me many of the essential concepts. Your clear explanations helped me understand how the different components of a website work together. Thank you so much for your guidance and for making the learning process easy to follow. ❤️

This is one of the best HTML and CSS courses I've taken. The instructor explains concepts clearly and builds everything step by step instead of just giving code to copy. I especially enjoyed building a real project from scratch because it helped me understand how HTML, CSS, Flexbox, Grid, responsive design, and website optimization all work together. One thing I really appreciated is that this course doesn't just teach coding it also teaches how to design a website with good design principles. I learned how to choose layouts, spacing, typography, colors, and other design ingredients that make a website look professional and user-friendly. Thank you for creating such a high-quality course. I highly recommend it to anyone who wants a strong foundation in HTML, CSS, and modern web design.

Amazing course! Lecturer has good english, no rubbish code, good explanations (images and text), doable challenges, there is a content given for each page that you build, solutions for each challenge to double check yourself, also it looks that the instructor is knowledgable about the topic. At this moment I have finished a quarter of all lectures but I don't think I'll change my mind.
By Diego Pereira on 5/5/2026
This course could've been shorter if the teacher had good speaking skills. It was very hard to go through the lessons because of that. Also, I felt he overexplained things that aren't important for beginners. I planned on buying his other courses but will no longer do that.
By Paulo Márcio Botelho Fraga Santos de And on 4/24/2026
An excellent course to start your learning journey in front-end web development. The instructor is very didactic, so everything starts off very easily, and with each lesson, you begin to create nicer and more complex components. In the last section, you create a real-world landing page from scratch to deployment, providing a very good practical experience, especially for beginners. I'm already an experienced back-end developer; therefore, it was an easygoing learning process, but I have the feeling that someone who has never programmed before will do great in this course. Thanks, Jonas, for everything; it was a very nice course!
By Olaf Meuwese on 3/14/2026
Very professional and elaborate course on the fundamentals of HTML and CSS. It's so well done! The concepts are very clearly explained and the examples are hands-on enough to get started with it. It's better than most tutorials because the depth of the explanations are so good that it will leave you with more than the feeling of "I can do exactly as the tutorial did but nothing more"
By Jorge Estuardo Polanco Cortez on 2/16/2026
This course has been amazing and truly helpful. I now understand many concepts that I struggled with before. Thank you for the time and effort you put into the explanations and challenges. Even though things move very fast, I feel much more confident now.
By Ilyas on 2/5/2026
A huge thank you for this amazing course! ⭐️ It was truly wonderful and incredibly interesting. I really enjoyed every moment and learned so much. Special thanks to Jonas! I also want to give a big shoutout to the teacher, Sebastian Neferu, who patiently answers every question that comes up. Sebastian Neferu is an incredible person who gives truly valuable, helpful, and clear answers. He's so responsive and a pleasure to interact with. Big thanks to both Sebastian Neferu and Jonas Schmedtmann! ❤️
