HTML Basics

Introduction to HTML

HTML (HyperText Markup Language) is the foundation of web development. It provides the structure and content of web pages through a system of tags and attributes.

Document Structure

Every HTML document follows a basic structure with html, head, and body tags defining the overall framework.

Text Elements

HTML provides various text elements like headings, paragraphs, and formatting tags to organize content.

Semantic HTML

Using semantic elements like header, footer, and article improves accessibility and SEO.

Code Example

                    <!-- Basic HTML Structure -->

                    <!DOCTYPE html>

                    <html lang="en">

                    <head>

                      <meta charset="UTF-8">

                      <title>Page Title</title>

                    </head>

                    <body>

                      <h1>My First Heading</h1>

                      <p>My first paragraph.</p>

                    </body>

                    </html>

Lists, Links & Images

Connecting Content

Creating connections between content is essential for navigation and user experience. HTML provides several ways to link resources and organize information.

Ordered Lists

Numbered lists for step-by-step instructions or ranked content using the <ol> and <li> tags.

Unordered Lists

Bulleted lists for items without a specific sequence using the <ul> and <li> tags.

Image Embedding

Adding visual content to web pages using the <img> tag with src and alt attributes.

CSS Introduction

Styling Web Pages

CSS (Cascading Style Sheets) is used to control the presentation and layout of web pages, separating content from design.

Selectors & Properties

CSS uses selectors to target HTML elements and properties to define their visual presentation.

Box Model

Every element is represented as a rectangular box with content, padding, border, and margin areas.

Colors & Typography

CSS provides extensive control over colors, fonts, and text properties to create visually appealing designs.

Box Model & Layout

Understanding Layout

The CSS Box Model is fundamental to understanding how elements are sized and spaced on a web page.

Box Properties

Content, padding, border, and margin properties control an element's dimensions and spacing.

Flexbox

A one-dimensional layout model that distributes space and aligns items efficiently.

CSS Grid

A two-dimensional layout system for creating complex responsive web design layouts.

Responsive Design
