Free online course Approximately 8 hours of self-study

Learn the basics of web development. On this course, you will first build a website using HTML and then style it with CSS and make it interactive using JavaScript.

Along the way you'll learn about the box model, which describes how websites are laid out by browsers, and about the Document Object Model, which your JavaScript code will interact with to dynamically change your web pages.

In the final week, you'll finish by making a quiz web page and then you will demonstrate your new skills by making your own website.

For the week on JavaScript, you need to be comfortable with using functions with parameters and return values. We recommend that you take our Programming 102 course if you are unsure.
