Web Development with HTML, CSS and JavaScript – Topic-Wise Notes

HTML (HyperText Markup Language) is the foundation of every web page. It uses tags to define the structure of content such as headings, paragraphs, links, images, and lists. In the class 9 computer chapter 5 html tags section, students learn essential tags like <h1> to <h6>, <p>, <a>, <img>, and <table>, along with their attributes.

  • HTML documents always start with a <!DOCTYPE html> declaration
  • The <html>, <head>, and <body> tags form the basic skeleton
  • Tags can be nested to create complex page structures
  • Attributes like href, src, and alt add extra information to tags

CSS Basics

Cascading Style Sheets (CSS) control how a web page looks — colors, fonts, spacing, and layout. Students studying 9th class computer html and css notes learn three main ways to apply CSS: inline, internal, and external styling. Selectors and properties are used to target specific HTML elements and apply visual styles.

  • Inline CSS is written directly inside an HTML tag using the style attribute
  • Internal CSS is placed inside a <style> tag within the <head> section
  • External CSS is written in a separate .css file and linked using <link>

JavaScript Basics

JavaScript adds interactivity and logic to a web page. The javascript basics class 9 computer notes portion introduces variables, data types, operators, conditional statements, and simple functions that respond to user actions like button clicks.
