About Course

Welcome to Web Development Essentials

Every website you use — from a search engine to your school portal — is built from the same three core technologies: HTML, CSS, and JavaScript. This course takes you from complete beginner to confidently building and publishing your own responsive, accessible websites, following the practices used by professional developers worldwide.

You will work through five modules. Each module contains a detailed reading lesson followed by a short knowledge-check quiz. When you finish all five, you sit a comprehensive final certification exam. Your progress and results are recorded automatically in your student dashboard.

How this course works

  • Learn — read the lesson and study the examples and code snippets.
  • Check — take the short module quiz; retry as many times as you need.
  • Certify — pass the final exam (70% required) to complete the course.
