HTML and CSS Basics

HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are the cornerstones of web development. HTML structures the content of web pages, while CSS styles them.

HTML Example: Basic Structure

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>The Educative - My First Web Page</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <header>
        <h1>Welcome to The Educative</h1>
        <nav>
            <ul>
                <li><a href="#home">Home</a></li>
                <li><a href="#about">About</a></li>
                <li><a href="#contact">Contact</a></li>
            </ul>
        </nav>
    </header>
    <main>
        <section id="home">
            <h2>Home</h2>
            <p>This is the home section of The Educative.</p>
        </section>
        <section id="about">
            <h2>About</h2>
            <p>This is the about section of The Educative.</p>
        </section>
        <section id="contact">
            <h2>Contact</h2>
            <p>This is the contact section of The Educative.</p>
        </section>
    </main>
    <footer>
        <p>&copy; 2024 The Educative</p>
    </footer>
</body>
</html>

CSS Example: Basic Styling

body {
    font-family: Arial, sans-serif;
    margin: 0;
    padding: 0;
}

header {
    background-color: #333;
    color: white;
    padding: 1rem;
}

nav ul {
    list-style-type: none;
    padding: 0;
    display: flex;
}

nav ul li {
    display: inline;
    margin-right: 1rem;
}

nav ul li a {
    color: white;
    text-decoration: none;
}

section {
    padding: 2rem;
    border-bottom: 1px solid #ccc;
}

footer {
    background-color: #333;
    color: white;
    text-align: center;
    padding: 1rem;
}

Responsive Design

Responsive design ensures that web pages look good on all devices by using fluid grids, flexible images, and media queries.

CSS Example: Media Queries

@media (max-width: 768px) {
    nav ul {
        text-align: center;
    }

    nav ul li {
        display: block;
        margin-bottom: 0.5rem;
    }
}

HTML Example: Responsive Images

<img src="image.jpg" alt="The Educative Example Image" style="width: 100%; height: auto;">

CSS Grid and Flexbox

CSS Grid and Flexbox are powerful layout systems that provide more control over how elements are arranged on the page.

CSS Grid Example

.container {
    display: grid;
    grid-template-columns: repeat(3, 1fr);
    gap: 1rem;
}

.item {
    background-color: #f4f4f4;
    padding: 1rem;
    border: 1px solid #ccc;
}

HTML Example: Grid Layout

<div class="container">
    <div class="item">Item 1</div>
    <div class="item">Item 2</div>
    <div class="item">Item 3</div>
</div>

CSS Flexbox Example

.container {
    display: flex;
    justify-content: space-around;
}

.item {
    background-color: #f4f4f4;
    padding: 1rem;
    border: 1px solid #ccc;
}

HTML Example: Flexbox Layout

<div class="container">
    <div class="item">Item 1</div>
    <div class="item">Item 2</div>
    <div class="item">Item 3</div>
</div>

JavaScript Basics

JavaScript adds interactivity to web pages. Here’s an overview of essential concepts:

JavaScript Example: Variables and Functions

// Variables
let name = 'John';
const age = 30;

// Function
function greet(name) {
    return `Hello, ${name}!`;
}

console.log(greet(name)); // Output: Hello, John!

JavaScript Example: Event Handling

<button id="myButton">Click Me</button>
<script>
document.getElementById('myButton').addEventListener('click', function() {
    alert('Button was clicked!');
});
</script>

Popular Libraries and Frameworks

Libraries and frameworks like React and Vue.js simplify complex tasks and enhance productivity.

React Example

// App.js
import React from 'react';

function App() {
  return (
    <div>
      <h1>Hello, React!</h1>
      <p>This is a basic React application.</p>
    </div>
  );
}

export default App;

Vue.js Example

<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Vue.js Example</title>
</head>
<body>
    <div id="app">
        <h1>{{ message }}</h1>
    </div>
    <script src="https://cdn.jsdelivr.net/npm/vue@2"></script>
    <script>
      new Vue({
        el: '#app',
        data: {
          message: 'Hello, Vue.js!'
        }
      });
    </script>
</body>
</html>
