HTML Basics

  • HTML (Hypertext Markup Language): Language used to create websites, displayed via browsers. Essential for all types of web technologies.
  • Crucial Tags: Heads (e.g., <header>, <footer>, <main>, etc.) are used for segmenting a webpage for better SEO (Search Engine Optimization) and readability.

Structure of a Web Page

  • Client-Server Model: Browser requests HTML, CSS, and JavaScript from the web server. The browser processes these files and displays the web page accordingly.
  • Head Section: Contains metadata, title, and links to CSS and JavaScript files. Essential for SEO and web resources.
  • Body Section: Contains content that will be rendered on the web page like text, images, and other elements.

HTML Development Tools

  • Text Editors: Tools like VS Code, Sublime Text, and Notepad++ help in writing HTML efficiently by providing syntax highlighting, autocompletion, and integrated development environment features.
  • Extensions and Add-ons: Useful in enhancing productivity, like Live Server in VS Code for real-time testing of web pages.
  • Templates and Boilplates: Ready-made, reusable code templates that make the setup process faster and easier.
