9 Best CSS Courses to Learn Online in 2021 | A Detailed List

CSS (Cascading Style Sheets) is one of the essential elements of web development. Without CSS, creating a professional website or web application would be near impossible.

Therefore, CSS is one of the most vital technologies of web design that no one can overlook.

If you want to become a front-end developer or web designer, mastering CSS is one of the most important career skills, along with HTML and JavaScript. Back-end developers will also find CSS useful, as they can better communicate with their front-end peers.

Furthermore, WordPress users who have no programming experience may also be interested, as you can create a customized styling for your site.

In this post, I am going to provide the best selections of online CSS courses. A high-quality online course along with a self-practice will help you master CSS in no time.

Things You Should Know

Compared to other programming languages, CSS is not too challenging to learn. Still, you may need several months or even a year to use CSS like a professional.

You don’t need any background knowledge to learn CSS because beginner courses will teach HTML as well. The only thing you need is a decent computer.

There are two main types of CSS courses: Comprehensive and Project-based

Comprehensive courses will teach you CSS concepts first and move to the projects in the second half. You will code along with your instructor step-by-step.

Project-based courses will teach you how to use CSS practically. You will learn by creating numerous real-world projects that will help you accumulate your web design skills as you progress.

However, some of them are not for beginners. You have to know HTML, CSS, and even JavaScript beforehand.

In my opinion, if you want to learn only basic concepts, taking a high-quality, comprehensive course will suffice.

If you want to improve your CSS skills beyond the beginner level or need more practice before launching your web development career, you will need a project-based course that teaches advanced CSS skills such as Flexbox in-depth.

Most of the courses I recommend are on the Udemy platform. Udemy frequently offers discounts. You should take that opportunity to buy them at a 90% discount on the original price.

Best Beginner CSS Courses

These are CSS courses for a beginner. You can select any online course you want, as all courses will teach you HTML, which is a prerequisite for learning CSS.

1. Modern HTML & CSS From The Beginning (Including Sass)

Brad Traversy, a full stack developer with more than a decade of experience, creates this comprehensive HTML and CSS course. If you want to build excellent web pages from scratch, this course is one of your best options.

Rating: 4.7/5.0, Students: 47,000

Comments and Tips

This course is an excellent introductory course for CSS and web design in general. Brad provides a good HTML tutorial of 2 hours, which is more than adequate for an absolute beginner to understand this markup language enough to progress to CSS.

Therefore, you won’t need an HTML course elsewhere.

The rest of the video content is comprehensive and covers almost everything from essential to advanced CSS. Brad’s voice is clear and 100% understandable, even to non-native speakers.

The only downside of this course is Brad has not updated the videos for almost a year, so some reviewers note that some knowledge he taught is already outdated. I hope he updates the course soon.

2. Build Responsive Real World Websites with HTML5 and CSS3

This project-based course on Udemy by Jonas Schmedtmann will teach you the basics of web design. Jonas is a full-stack developer who creates many excellent courses on Udemy with almost a million students in total.

Thus, it is always worth putting his course into consideration.

Course Content

In this course, you will learn HTML and CSS up to the level that you can build a responsive real-world website of your own.

  • Basic HTML and CSS (Structure, Links, Images, Attributes, Classes)
  • Web design fundamentals (typography, color, icon, layout)
  • Responsive design with media queries – Learn to create a website that can be viewed beautifully from different screen sizes.
  • Building a responsive navigation for a web page (jQuery introduced)
  • Animation, Flexbox, and optimization of your site
  • A colossal website project (5.30 hours in total)

The video lectures are 12 hours long. Rating: 4.6/5.0, Students: 214,000+

Comments and Tips

As a project-based course, most of its content inclines toward the project. You will spend most of your time working on your responsive site along with your instructor. If you want to learn by doing, you will like this course.

The course is well-structured. Numerous slides will guide you through the course, especially on the project part. Jonas’s voice is also apparent. You can understand him with ease.

However, this course teaches only necessary to intermediate CSS. If you want to learn advanced CSS, you need to take Jonas’s second course on that topic.

3. HTML & CSS Tutorial and Projects Course

Anyone who wants an all-in-one beginner course will find this tutorial to be the best online option available. John Smilga, an experienced web developer, creates this highly-detailed course on Udemy for those who want to learn HTML and CSS by heart.

Course Content

The video length is 41 hours in total, which far outpaces other online courses.

  • HTML Tutorial – VS Code (a text editor) Introduction, Document Structure, Images, Texts, Lists and many more
  • CSS Tutorial – CSS selectors, syntax, inheritance
  • Colors, Units, Typography, Background
  • Positions, Float, and Media queries
  • CSS Animation, Transform, Transition
  • CSS Flexbox and Grid
  • and many more

Besides, you will build several websites by following John’s guidance. You will start with simple web pages and finish the course with full-blown sites.

Rating: 4.5/5.0, Students: 7,400+


I have taken this course myself, so below is the overview of the pros and cons I found.


  • Beginner-friendly. John’s pace is suitable for all beginners in web development. He is not too fast or too slow. Everything he explains is straightforward and detailed, especially the VS Code part, which many other instructors ignore.
  • Truly comprehensive. John provides you with the best of both worlds. His course has an extensive theoretical part that explains CSS concepts and a project part that he will guide you to build several websites.
  • Step-by-step learning. There is no sudden spike of difficulty in this course. You will learn CSS one step at a time and gradually accumulate skills needed for a web developer or a web designer.


  • John has a slightly muffled voice. Thus, unfortunately, sometimes it isn’t easy to understand him.
  • No sass stuff

From an overall point of view, John’s CSS course is marvelous. I highly recommend it. However, it would help if you watched the preview first to test whether you can understand him.

4. Web Design for Beginners: Real World Coding in HTML & CSS

This is an HTML & CSS course by Brad Schiff (different Brad from the first course.) He is a front-end developer who has tons of experience teaching web development to Fortune 100 employees.

  • Selectors, box models, basic styling
  • Typography and background

This course has 11 hours of content available.

Rating: 4.6/5.0, Students: 53,000+

Comments and Tips

This one will suit your learning style for those who want a concise introductory course on HTML and CSS. Brad will cover all significant concepts and provide short projects for you to complete.

Furthermore, you will also grasp how to use CSS and other web-development elements such as JavaScript and Bootstrap.

However, this course does not drill deep into any concepts. If you want to learn advanced CSS stuff, you have to take another course on Udemy. Skipping this course altogether and choosing a better alternative can be a decent decision as well.

Still, the sound quality of each video is flawless. Brad’s voice is effortless to understand.

5. Responsive Web Design Essentials – HTML5 CSS3 Bootstrap

For people who want to focus on responsive web design, this project-based course by Daniel Scott, a web designer, is probably one of the best online.

Despite being a project-based course, you don’t need to know any HTML or CSS to take it.

Course Content

In this course, you will learn everything by doing a project. Daniel will teach you to build a site for a restaurant, a bike repair service, a portfolio, and a yogurt store. Each website will increase in difficulty, as he will teach you to add more features to it.

For example, the third project will add a responsive design for views over any screen size, while the fourth will add Bootstrap components to create more elaborate menus, carousels, and cards.

In total, the video length is 16.5 hours long. Rating: 4.7/5.0, Students: 9,400+

Comments and Tips

Anyone seeking real-world experience will appreciate this course. Your skills will improve step-by-step after finishing a project.

However, compared to comprehensive courses, this one is less well-structured.

You should not expect an instructor to focus on a specific CSS concept, such as Flexbox, one at a time, but you will learn how each significant CSS component works together. This knowledge is beneficial for building a modern responsive website.

Daniel usually responds to questions and comments. His voice is also flawlessly comprehensible. Overall, I think this is one of the best online CSS courses on Udemy.

6. Professional Certificate in Front-End Web Developer (edX)

This edX program teaches much more than regular CSS, as you will learn all basics needed for a web developer career. You will learn with top experts from the World Wide Web Consortium (W3C), an organization that provides an international web standard.

There are no prerequisites for this course.

Course Content

The program comprises five minor courses:

  1. CSS Basics: Fundamental features, including those related to fonts, colors, and layout.
  2. HTML5 and CSS Fundamentals – Introduction to HTML & CSS (Attributes, Images, Selectors, Grid Flexbox)
  3. HTML5 Coding Essentials and Best Practices – This course is particularly interesting. You will dive deep into HTML5 and understand the best practices related to graphics, animations, forms, and basic APIs.
  4. HTML5 Apps and Games – You will learn about advanced HTML5 multimedia, game development and file uploads
  5. JavaScript Introduction – You will understand basic JavaScript to add interactivity to your websites

W3C recommends spending 5-7 hours per week on the courses, and you will complete them in 7 months.

Auditing all five courses is free. Still, if you want a professional certificate and your assignments to be graded, you need to pay $895.5 in total.

Comments and Tips

This program drills deep on HTML5 and CSS, especially HTML5, that you may not find better online courses elsewhere.

Furthermore, as you learn from experts who develop the best standard, you will be a well-trained programmer who follows the best practices clients and companies prefer.

The only downside of this program is that it is not well-structured. You should not start learning by taking the first course because you should learn HTML before CSS.

On the other hand, you should consider the second course, which teaches you HTML5 first, and then go back to the first course.

After these two courses, you should learn Course 5 or JavaScript introduction, as both Course 3 and 4 require basic JavaScript knowledge (all indicated in the minor course’s pages.)

In other words, the order that you should take the courses is 2-1-5-3-4, not 1-2-3-4-5.

I don’t understand why they sort courses like this, which is burdensome for learners.

Top Advanced CSS Courses

These courses will not teach HTML but will drill deep into advanced topics such as Flexbox, CSS Grid, and Sass. You have to understand how CSS works with HTML before taking these online courses.

7. CSS – The Complete Guide 2021 (incl. Flexbox, Grid & Sass)

This is a complete CSS course by Maximilian Schwarzmüller, a self-taught developer who becomes a popular instructor on Udemy. His courses now have more than 1.3 million students in total.

In this course, he will teach CSS from the very beginning. If you want an all-inclusive course on CSS, you should seriously consider this one.

Comments and Tips

This course is all-rounded. Max will drill deep into all CSS concepts you should know. Flexbox, Grid, and Sass are adequately covered in this course.

I have taken some online courses with Max. He is one of the best instructors I ever had. His way of teaching is always straightforward. It is effortless to understand the content.

Therefore, I am confident that he will not be disappointed. If you want to learn advanced CSS, I highly recommend him to you.

8. Advanced CSS and Sass: Flexbox, Grid, Animations, and More!

If you like how Jonas teaches, this is another course by him. He will deal with advanced CSS, a topic which he does not cover in his beginner course.

Jonas emphasizes that you need an intermediate knowledge of HTML and CSS to start learning efficiently.

Course Content

Jonas’s teaching approach is different from the first course. You will learn advanced CSS by building three large projects by utilizing various CSS technologies.

Below is what you will learn and build on the project

  • Create a header and animated button for your website
  • How CSS works behind the scenes
  • Introduction to Sass and NPM
  • Building a custom grid, about, features, tours, stories sections along with a navigation bar and a pop-up
  • Advanced responsive design (Writing media queries and creating responsive images)
  • Advanced Flexbox and CSS Grid layout
  • and many more

There are more than 28 hours of video content in total. Jonas also provides high-quality subtitles (not auto-generated by Udemy) to help you understand what he said.

Rating: 4.8/5.0, Students: 123,000+

Comments and Tips

Jonas’s course is excellent for anyone who wants to learn advanced CSS. He teaches CSS tricks, techniques, and related technologies in-depth for you to understand and use them in the real scenario.

Each project is practical and adaptable. You can develop these projects further or at least keep them in your portfolio.

For those who took Jonas’s first course, feel free to buy this one, as both courses are 100% different. Getting this course at a 90% discount would be a big plus.

9. Learn Advanced CSS with Front End Masters

Those who want to learn advanced CSS with the cream of the crop could subscribe to Front End Masters, a website that assembles many top experts to teach front-end stuff to everyone.

Many of them are working at top tech companies or institutions, such as LinkedIn, Spotify, or even Harvard.

Front End Masters – learn advanced css with a professional

Course Content

The website has several advanced CSS courses, including:

  • Advanced CSS Features
  • CSS Grid and Flexbox for Responsive Web Design
  • Sass Fundamentals
  • Advanced CSS Layouts
  • Motion design with CSS

Each course is 4-10 hours long and has multiple challenges that help learners advance their skills.

A monthly subscription will cost $39 per month. However, if you subscribe for a yearly plan, you will get two months free, or around 20% off from the original price.

Within the same subscription plan, you will be able to access all content (React, Angular, and many more web development and programming courses) along with HTML & CSS.

Comments and Tips

Front End Masters’ online courses are all in-depth and not for beginners. You will need to learn basic CSS before taking theirs.

However, learning from experts is always great. You will also learn how to think like a skilled programmer, which will help you significantly in coding, especially if you want to pursue a development career.

Thus, if you want to understand CSS by heart, Front End Masters is 100% worth your consideration.

Still, some videos are aged-many dates from 2017 or even before. The pricing is also expensive compared to alternatives on Udemy.

Free CSS Courses

Freecodecamp – This free course is probably the best available. You will learn by following text instructions and code along with them. As there are many practice exercises on the platform, I suggest using Udemy courses to improve your HTML & CSS understanding optimally.

After you learn advanced CSS, your next stop will be JavaScript, a programming language vital to building a responsive real-world website with unlimited features.
