What is HTML? ▼

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.

Key features of HTML:

  • Defines the structure of web content
  • Works with CSS for styling
  • Works with JavaScript for interactivity
  • Uses semantic elements for better accessibility
Getting Started with CSS ▼

CSS (Cascading Style Sheets) is used to style and layout web pages. It allows you to control colors, fonts, spacing, and positioning of HTML elements.

You can apply CSS in three ways:

  • Inline styles directly in HTML elements
  • Internal stylesheets within the <style> tag
  • External stylesheets linked via <link> tag
JavaScript Basics ▼

JavaScript is a programming language that adds interactivity to web pages. It can manipulate HTML elements, respond to user events, and communicate with servers.

Common JavaScript tasks:

  • Validating form data
  • Changing HTML content dynamically
  • Controlling multimedia
  • Creating animations and effects
