📘 HTML – Structure of the Web
What is HTML? HTML stands for HyperText Markup Language. It provides the basic structure of web pages using elements like headings, paragraphs, links, images, etc.
Why HTML? Every website starts with HTML. It’s the skeleton before adding design or behavior.
🗓️ Day 1–3: HTML Basics
- Tags: <h1>, <p>, <a>, <img>, <ul>, <ol>
- Attributes: href, src, alt, title
- Forms: <form>, <input>, <textarea>, <button>
<!DOCTYPE html>
<html>
<head>
<title>Welcome</title>
</head>
<body>
<h1>Hello World!</h1>
<p>Welcome to my first web page.</p>
</body>
</html>
📌 Tip:
Use semantic tags like <article>, <section>, <nav> for better structure and SEO.
🎨 CSS – Styling and Layout
What is CSS? CSS (Cascading Style Sheets) styles the structure built with HTML – like colors, fonts, layout, and animations.
Why CSS? Without CSS, all websites would look plain. It gives life to your content.
🗓️ Day 4–6: Styling Basics
- Selectors: element, class, ID
- Properties: color, font-size, margin, padding, border
- Responsive Design: Media queries
body {
background-color: #f9f9f9;
color: #333;
font-family: Arial, sans-serif;
}
🗓️ Day 7–9: Box Model & Flexbox
Understand spacing, alignment, and layout with the box model and Flexbox.
⚙️ JavaScript – Making It Interactive
What is JS? JavaScript adds interactivity – clicks, inputs, animations, and more.
🗓️ Day 10–12: JS Basics
- Variables: let, const
- Functions: function greet() {...}
- Events: onclick, onsubmit
function greet() {
alert("Hello, user!");
}
🗓️ Day 13–15: DOM & Projects
Use JavaScript to change HTML and CSS dynamically with the Document Object Model (DOM).
