The Building Blocks of Web Development

  • HTML (HyperText Markup Language): The skeleton of a website. Defines the structure and content.
  • CSS (Cascading Style Sheets): The styling layer. Controls the layout and appearance.
  • JavaScript: Adds interactivity. Makes websites dynamic and responsive to user actions.

Front-end vs. Back-end Development

  • Front-end Development: Focuses on the client side, dealing with everything users interact with directly in their web browser. It involves the design and development of interfaces using HTML, CSS, and JavaScript.
  • Back-end Development: Manages the server side, including databases, servers, and applications. It ensures that data or services requested by the front end are delivered through application programming interfaces (APIs).

Hands-on Examples and Exercises

  • HTML: Create a basic webpage with paragraphs, headings, links, and images.
  • CSS: Style the webpage with different colors, fonts, and layouts.
  • JavaScript: Add a simple script to change a webpage's content based on user input.
