Free online courseHTML, CSS and JavaScript

Course Description

Turn ideas into interactive websites by learning the three core technologies of the web: HTML for structure, CSS for design, and JavaScript for behavior. This free online course guides you from the fundamentals of clean page layout to creating responsive, engaging interfaces that work across devices. You will gain practical confidence in writing semantic HTML5, organizing content for readability and accessibility, and choosing the right elements to make pages easier to navigate and maintain.

On the design side, you will learn how CSS brings a site to life: controlling typography, spacing, alignment, and visual hierarchy while keeping styles consistent and easy to scale. You will work with modern layout techniques such as Flexbox and grid-style thinking, explore positioning options, and understand how to manage defaults using resets so designs render reliably across browsers. You will also develop an eye for real-world details such as text effects, image handling for quality and performance, and the small styling decisions that make a site feel professional.

As you progress, the course connects design with usability by focusing on mobile-friendly practices and responsive behavior, including strategies for adapting layouts to different screens and even improving print styles. You will learn to build structured tables and user-friendly forms, working with common input types and interface controls that make data entry smoother. Multimedia concepts are introduced so you can better understand how audio and video delivery works on the web, including why codecs matter for efficient transmission and compatibility.

Finally, you will bring pages to life with JavaScript, developing a clear understanding of client-side scripting, how to target elements in the document, and how logic, operators, and loops drive dynamic features. You will practice event-driven interactions, explore functions (including anonymous functions), and work with the document structure to update content and styles programmatically. By the end, you will be able to build more than static pages—you will be able to create experiences that respond to users, support real scenarios, and provide a strong foundation for further growth in web development.
