Welcome to the Building Blocks of the Internet, a seven-part course that looks at the fundamental technologies that make up websites and web pages. This course gives those who are new to web technologies an introduction to the following:

  • HTML
  • CSS
  • JavaScript
  • Network protocols focussed on HTTP
  • Network protocol security

You will learn what these technologies are, how they work and how to test them. So you can:

  • Work with these technologies to build your own testing project.
  • Quickly analyse web pages and test individual parts of a site.
  • Understand the underlying principles of the web that are used not just for web pages but in popular automation tools such as Selenium WebDriver.

Resources you'll use throughout this course:

  • Atom: a text editing tool.
  • JS Bin: A live pastebin for HTML, CSS & JavaScript and a range of processors.
  • WC3 Validator: This validator checks the markup validity of web documents.
