HTML (HyperText Markup Language) is the standard markup language used to create web pages. It provides the structure and content of websites by using a system of tags and elements that tell web browsers how to display text, images, links, and other media.

HTML works alongside CSS for styling and JavaScript for interactivity to create complete web applications.

Semantic HTML improves web accessibility and SEO by using meaningful tags that clearly describe their purpose:

  • <header> - Defines introductory content
  • <nav> - Groups navigation links
  • <main> - Specifies main content
  • <article> - Represents independent content
  • <footer> - Defines footer content

Follow these best practices when writing HTML:

  • Use semantic tags for better structure
  • Keep markup clean and indented properly
  • Always include alt text for images
  • Use proper heading hierarchy (h1, h2, etc.)
  • Validate your HTML code
  • Separate content from presentation (use CSS)
  • Make your site accessible to all users

HTML5 introduced many new features and improvements:

  • Native video and audio support
  • Canvas for drawing graphics
  • Improved form controls and validation
  • Geolocation API
  • Web Storage (localStorage, sessionStorage)
  • Semantic elements for better document structure
  • Improved accessibility features

HTML5 is now the current standard for web development and is continuously evolving.
