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.

You will be able to:

  • Produce a HTML web page using suitable tags and attributes
  • Explain the advantages of CSS compared to inline styling
  • Apply classes and ids to style a website
  • Model web pages using the box model
  • Demonstrate how to use the Document Object Model (DOM) to access an element of a web page
  • Produce an interactive website using JavaScript
