Comprehensive Notes
HTML5
HTML (HyperText Markup Language) is the backbone of web pages. Key tags include <div>, <p>, <a>, <img>, <header>, <footer>. Use semantic tags for accessibility and SEO. Forms use <form> with inputs, labels, and proper validation.
CSS3
CSS (Cascading Style Sheets) controls style and layout. Use selectors, classes, IDs, flexbox, grid, transitions, animations. Responsive design uses @media queries. Variables help maintain consistent colors and themes.
JavaScript
JavaScript makes websites interactive. Key topics: DOM manipulation, event listeners, fetch API, ES6 features like arrow functions, let/const, template literals. Async/await, promises, and localStorage are critical for modern apps.
Python
Python is beginner-friendly and versatile. Covers variables, data types, loops, conditionals, functions, OOP, file I/O, libraries like requests, pandas, numpy, and frameworks like Flask/Django. Use Python for scripting, automation, and AI-assisted coding.
Ethical Hacking & OSINT
Learn penetration testing legally: footprinting, scanning, vulnerabilities, exploitation in controlled environments. OSINT covers public data gathering, ethical recon, social media, and AI-assisted tools like Maltego for data correlation.
Advanced Labs
HTML/CSS Project
