This documentation covers the basics and advanced techniques of web development.
It is designed for developers at all levels.
Understanding the structure of web development is essential to creating effective websites.
Each section explains a fundamental aspect of web development.
Let's start with the basic technologies: HTML, CSS, and JavaScript.
<html>
<body>
<p>Welcome to the web</p>
</body>
</html>
- Introduction to HTML
- CSS basics
- Introduction to JavaScript
- Understanding the DOM
- Advanced techniques
HTML stands for HyperText Markup Language.
It forms the structure of a web page.
HTML elements are the building blocks of a webpage.
Tags such as <html>, <body>, and <h1> define the structure.
HTML is essential for creating content on the web.
<html>
<body>
<h1>This is a header</h1>
<p>This is a paragraph</p>
</body>
- HTML document structure
- Common HTML tags
- Attributes in HTML
- Embedding media
- Semantic HTML
CSS stands for Cascading Style Sheets.
It controls the presentation of HTML elements.
CSS allows you to style text, layout, colors, and much more.
By linking CSS to HTML, you can create visually appealing pages.
CSS can be written inline, internally, or externally.
body { color: #333; }
h1 { font-size: 2em; }
.container { width: 80%; margin: auto; }
#header { background-color: #f4f4f4; }
a { text-decoration: none; }
- CSS selectors
- Styling text and fonts
- Box model
- Layout with Flexbox
- Responsive design
JavaScript is a programming language used to create dynamic content.
It enables interactive features like buttons, forms, and animations.
JavaScript can manipulate HTML and CSS to modify web pages.
It is essential for modern web development.
JavaScript code is executed by the browser's JavaScript engine.
let x = 10;
const greeting = "Hello World";
document.getElementById("myElement").innerText = greeting;
function myFunction() { alert('Hello!'); }
console.log("Hello World");
- Variables and Data Types
- Functions and Events
- DOM manipulation
- Loops and conditionals
- JavaScript libraries
Advanced techniques involve using more sophisticated tools and concepts.
Responsive design, JavaScript frameworks, and server-side development are all part of this.
Modern web applications often use frameworks like React or Angular.
Backend development with Node.js and databases is also a key area of focus.
Understanding APIs and AJAX is crucial for dynamic web apps.
import React from 'react';
const App = () => <h1>Welcome to React</h1>;
const fetchData = async () => { const response = await fetch(url); }
npm install react
const express = require('express');
