Welcome to the MDN Learning Area. This set of articles aims to provide complete beginners to web development with all they need to start coding simple websites.
The aim of this area of MDN is not to take you from "beginner" to "expert" but to take you from "beginner" to "comfortable". From there you should be able to start making your way, learning from the rest of MDN, and other intermediate to advanced resources that assume a lot of previous knowledge.
If you are a complete beginner, web development can be challenging — we will hold your hand and provide enough detail for you to feel comfortable and learn the topics properly. You should feel at home whether you are a student learning web development (on your own or as part of a class), a teacher looking for class materials, a hobbyist, or someone who just wants to understand more about how web technologies work.
Important: The content in the Learning Area is being added to regularly. If you have questions regarding topics you'd like to see covered or feel are missing, see the Contact us section below for information on how to get in touch.
Where to start
- Complete beginner: If you are a complete beginner to web development, we'd recommend that you start by working through our Getting started with the Web module, which provides a practical introduction to web development.
- Specific questions: If you have a specific question about web development, our Common questions section may have something to help you.
- Beyond the basics: If you have a bit of knowledge already, the next step is to learn HTML and CSS in detail: start with our Introduction to HTML module and move on to our Introduction to CSS module.
Note: Our Glossary provides terminology definitions.

Getting our code examples
The code examples you'll encounter in the Learning Area are all available on GitHub. If you want to copy them all to your computer, the easiest way is to:
- Install Git on your machine. This is the underlying version control system software that GitHub works on top of.
- Sign up for a GitHub account. It's simple and easy.
- Once you've signed up, log in to github.com with your username and password.
- Open your computer's command prompt (Windows) or terminal (Linux, MacOSX)
- To copy the learning area repo to a folder called learning-area in the current location your command prompt/terminal is pointing to, use the following command:
git clone https://github.com/mdn/learning-area
- You can now enter the directory and find the files you are after (either using your finder/file explorer, or the cd command).
You can update the
learning-area repository with any changes made to the master version on GitHub with the following steps:
- In your command prompt/terminal, go inside the
cd, for example if you were in the parent directory:
- Update the repository using the following command:
If you want to get in touch with us about anything, the best way is to drop us a message on our mailing lists or IRC channels. We'd like to hear from you about anything you think is wrong or missing on the site, requests for new learning topics, requests for help with items you don't understand, or anything else.
