Do you want to create a WordPress theme that really works? Would you like to learn how to edit a WordPress theme without suffering?
I know that searching the Internet for articles and tutorials is quite frustrating. But if you really want to learn everything about creating WordPress themes, you've found the right course! This course will pave the way for you to become an official WordPress theme developer.
Imagine yourself doing what you love most, whether at home or in your own company, being your own boss, and even earning top dollar! Good developers can earn from $3,000 to $15,000 creating a custom WordPress theme. So knowing how to create WordPress themes is synonymous with being able to earn very well, as this is currently one of the most sought-after skills on the market. WordPress is behind 30% of websites worldwide. In other words, it is a growing market!
If you are looking to earn extra money, or even want to work as a full-time freelancer, this course will prove to be perfect for you. It brings what I call a 'simplified approach' to the subject, because that's the way I tried to structure the course for you. I didn't have chances to learn in an easy way in the past, which is why I decided to make it as easy as possible for my students.
You won't have to go through all the tiresome and often useless research that I had to go through. Everything I learned is summarized in this course. It covers all the fundamental aspects of learning how to create a WordPress theme from scratch. You will be catapulted to a new professional level.
By the end of this course, you will have a solid foundation to become a skilled theme developer. You will be able to master a complete set of skills such as creating a theme independently, or editing a third-party WordPress theme. Take a look at what my student Walton Jones has to say:
"Three weeks ago, I knew very little about WordPress. Today I am laying the finishing touches on a WordPress site for a client that they are very pleased with. This is all thanks to this course. Marcelo is an awesome, responsive teacher who was always quick to answer my questions."
Here are some of the things you no longer need, because all the necessary knowledge will already be at your fingertips:
You no longer need to read pages and more pages of documentation to understand how to create WordPress themes;
You no longer need to waste time reading long tutorials on the web;
You no longer have to be bored looking for or watching useless content on YouTube.
What exactly will I learn?
The course will be divided into two moments.
Moment 1:
This first part will have 6 sections, in which we will create the WordPress theme from start to finish. We will talk about topics such as:
WordPress installation using Local and/or Docker. Yes, we stopped using Xampp for everyone's sake and included Local (the favorite installation tool for WordPress devs at the moment) and Docker;
template hierarchy, enqueueing of scripts and stylesheets;
menu creation, including responsive menus just using CSS, HTML and Javascript. Yes, at last, now the theme course will no longer depend on any plugin to work;
the WordPress loop, both the default loop and the custom loop (using the WP_Query class);
inclusion of several types of theme_support;
widget areas, permalinks, the main template files, the various types of pagination;
template parts and conditional tags (another new subject);
the powerful Theme Customizer;
theme translation and security. Yes, I've included lessons about security in WordPress themes (!);
site migration from the local server to a remote server.
Moment 2:
In a second moment, there will be a bonus section with some complementary subjects, which will help you understand a little bit more about the theme creation universe, as well as introduce some trends regarding this subject.
We'll talk about page builders. We will introduce you to child themes, talk about Docker, and especially about Gutenberg (the block editor and new features brought by WordPress in versions 5.8 and 5.9, such as block-based themes, the theme.json file, etc.).
This is meant to get you started transitioning from what they are now calling "classic themes" to brand-new block-based themes. The course will not teach you how to create block themes yet, but it will be a good start.
How can you tell if this course is really different?
What makes this course unique is the versatility and benefits it delivers. This course brings you 69 highly comprehensive lessons, all carefully organized in sections, leaving no important subject behind.
But the best thing about the course is my willingness to help you. My biggest priority is to make sure that you get to the end of the course with no doubts. That's why the absolute majority of questions are answered within 24 hours, allowing you to study at your own pace with nothing to get in your way.
I am sure that other courses cannot afford to have students saying things like this:
"I'm almost done with my own theme, ran in to an issue, and Marcelo has responded back with very detailed, quick help. I don't know how he does it! (...) Marcelo has laid this course out well, when you come up to a snag do everything you can to research and fix it on your own, but if you can't he's there for you. That's huge for me and may be for you, too." (Ryan Johnson)
Ok... Does this course really work?
Yes. Many students who have been through this course have already got jobs, or are self-employed earning a good income. Again, I will let students who have been through the course answer this question:
"Excellent course! It teaches in a practical and simple way, easy to understand. Teacher Marcelo is great, and answers questions quickly too! Thanks to the course I even got a job as a Wordpress Theme Developer! (Robson Henrique Rodrigues)
"One of the best courses I've done in my life! (...) Because of this course, I got an opportunity in my job that earned me a raise! I'm very happy and fulfilled working with something I'm passionate about, which is WordPress programming. I recommend this course and Marcelo's others to everyone!" (Rebeca M.)

Sehr gut und einfach erklärt, sehr gut strukturiert. Ein paar Dinge sind aber nicht mehr ganz modern und könnten aktualisiert werden. Ich habe bisher nur Themes angepasst und Snippets aus der Community benutzt. Mir hat der Kurs Spaß gemacht und er konnte mir wirklich Wissen vermitteln bzw. mein Halbwissen vervollständigen :) . Zusätzlich animiert er, aktiv zu lernen und sich z.B. die Dokumentation von WordPress anzuschauen.
By Estevan Ruiz on 2/16/2025
This is a great primer on classic WordPress theme development. I appreciate Marcelo's focus on what you can do with code without relying on plugins. It really helped to see the patterns used to effectively utilize the WordPress core and implement custom options. The additional content on the block editor is a great bonus too. Although it seems that block-based themes will become the new standard, in reality, the tech is still new and will take a long time to be fully adopted. They say WordPress powers 40% of all websites. Just think of all those classic themes! The support won't go away any time soon. The content in this course is still relevant. So if you're looking to upskill and develop your own WordPress themes through code, this is the course for you!
By Alexandros Chrysovergis on 2/11/2025
This course was phenomenal! Mr. Vieira is an engaging instructor who explains every concept thoroughly and in a way that’s easy to understand. While the focus is on Classic Theme Development, the course also includes a concise yet comprehensive introduction to Block Theme Development which I found very interesting as I haven't experimented with Gutenberg a whole lot. I highly recommend this course to anyone looking to deepen their knowledge on WordPress. Thank you, Mr. Vieira for this amazing learning experience!

I recently completed the "WordPress Theme Development from Scratch 2.0" course on Udemy, and I cannot praise it enough! This course is an absolute gem for anyone looking to dive into WordPress theme development. The instructor's teaching style is exceptional. He breaks down complex concepts into easily digestible modules, making them accessible even for beginners. The pace of the course is just right, allowing you to absorb each topic thoroughly before moving on to the next. The hands-on approach is incredibly effective, and I found myself building a custom WordPress theme with confidence by the end of the course. One of the highlights of this course is its up-to-date content. WordPress is constantly evolving, and this course ensures that you're working with the latest technologies and best practices. Marcelo also provides practical insights into responsive design, and security considerations, which are invaluable for real-world projects. The course materials, including video lectures, code samples, and quizzes, are well-structured and thoughtfully organized. The downloadable resources and code snippets provided throughout the course are incredibly helpful and saved me a ton of time. What sets this course apart is Marcelo's passion for WordPress development. His enthusiasm is contagious, and it motivated me to go above and beyond in my learning journey. Additionally, the instructor is very responsive to questions and provides excellent support to students, creating a fantastic learning community around the course. I was particularly impressed with the depth of knowledge I gained about WordPress theme development. From understanding the WordPress core to creating custom post types and widgets, this course covers it all. I now feel confident in my ability to create bespoke WordPress themes for myself and my clients. I think the "WordPress Theme Development from Scratch 2.0" course on Udemy is a must-take for anyone interested in WordPress theme development. Whether you're a beginner or have some experience, you'll find immense value in this course. I can't recommend it highly enough – it's worth every penny, and more! Thank you to Marcelo for creating such an outstanding resource. I can't wait to put my newfound skills to use in the real world. This course deserves all five stars and then some!
By P S on 7/31/2023
Pro: Course content was good for learning all the basics of turning an HTML site into WordPress, and I liked that he warned us about using Google fonts. Con: I wasn't able to breeze through as quickly as I initially hoped because it was really hard to understand his English without having to use the subtitle feature, which made focusing exhausting. Eventually I got frustrated from relying on subtitles so I had to take a lot of breaks, but I understand that English is his second language so I can't take that part into consideration for my rating. If I can speak fluent Portuguese, I'm sure that this course would have actually been much easier to follow.

I am happy I purchased this course. I could easily follow it along. And I would happily recommend this course to anyone who is trying to create a custom WP theme from scratch, but who is not a programmer. One complaint. I got frustrated when in lesson 53 - Internationalization (part 3), suddenly I had to go through several php pages to implement those __( functions. It totally broke my flow of learning. It could have been covered ... differently. Probably at the end of the course, OR it would have been better if this feature was implemented ONLY for only 1-2 pages for learning purposes. Marcelo has done an awesome job!
By Captain Krik on 6/11/2021
As I expected, Marcelo has a clear and detailed teaching method. He uses techniques for developers who are already familiar with the code, without wasting time with notions that most courses always repeat. I learned new concepts and techniques, very useful for creating a website. I also strongly recommend the WooCommerce course which has the same qualities, indeed even more. Thanks Marcelo, you really are number one!
By Jose Padron on 1/19/2020
I recommend this course for beginners in the development of WordPress themes. Beginners will value this course more than people with previous knowledge of WordPress. Several plugins were used to implement some elements of the main layout of the course, namely, for the contact form, for the slider, for social media icons and for the responsive menu. My experience with the instructor in terms of the answers he offered to my questions was good. His answers were quick and timely, however, for one of them I couldn't solved the detail. In general I value as positive the experience and skills acquired in the course, I consider it will serve as a basis to develop the structure of my own themes in WordPress from scratch. As for the instructor, he is perceived as a methodical, analytical, calm, kind person, and concerned with transmitting the contents in an incremental way, to make learning less traumatized, simpler and more natural. Very good course, thanks to the instructor Marcelo…. Success !!!
By Ryan Johnson on 1/2/2019
This is my second time running through this course (the first time I copied his theme and now am making my own) and it hands down deserves 5 stars. I'm almost done with my own theme, ran in to an issue, and Marcelo has responded back with very detailed, quick help. I don't know how he does it! I started the class with basic wordpress, html, css, and bootstrap knowledge, which I would say is the perfect place to come from in hindsight. About half of the class was above my head on the first time through - keep up with it anyways! - and the second time through I'm stunned at how much more I understand. Each problem I had ended up being a huge learning experience, keep that in mind. Marcelo has laid this course out well, when you come up to a snag do everything you can to research and fix it on your own, but if you can't he's there for you. That's huge for me and may be for you, too.

Thank you for this excellent course, Marcelo! As I said in one of my questions, I used this knowledge in my first WordPress related contract, which I landed while in the middle of the course! I'm now in the running for my next one and am going to take the free time that I have while waiting on contract decisions to build my first theme that I plan to put up for sale. GREAT job on this course...I HIGHLY recommend it!
