Mastering HTML & HTML5: Complete Web Development Guide
Learn the essentials of HTML/HTML5, from basic tags and document structure to semantic elements, forms, and tables for modern web development.
HTML & HTML5 Syllabus
Level 1: Basic to Level 2: Intermediate Web Development
1. Introduction to Web & HTML
The Internet: A global network connecting computers worldwide.
Web Development: Creating websites & web applications.
HTML (HyperText Markup Language): The standard markup language for creating web pages.
Evolution: From basic HTML to HTML5 features.
2. HTML Document Structure
Every HTML document follows a tree-like structure known as the DOM. The <!DOCTYPE> declaration defines the document type. The <html> tag wraps all content. <head> contains metadata and title, while <body> contains the visible page content.
3. Basic HTML Tags
Headings: <h1> (Most important) to <h6> (Least important).
Paragraphs: <p> tag defines a block of text.
Separators: <br> for single line breaks, <hr> for horizontal rules.
Formatting: <strong> (Bold importance), <em> (Emphasized italics).
4. Organizing Content: Lists
Lists organize data linearly. <ul> (Unordered List) uses bullet points. <ol> (Ordered List) uses numbers or letters. <dl> (Description List) pairs terms with definitions.
The <a> tag defines a hyperlink, which is used to link from one page to another.
5. Links & Navigation Fundamentals
6. Images & Media
Images enhance visual appeal. The <img> tag is empty—it contains attributes only and no closing tag. The 'src' attribute defines the path, while 'alt' provides alternative text for accessibility.
7. Structured Data: Tables (Level 2)
<table>: The wrapper element.
<tr>: Defines a table row.
<th>: Header cell (bold & centered by default).
<td>: Standard table data cell.
Attributes: rowspan & colspan for merging cells.
8. Forms & Inputs
Forms collect user input. The <form> element defines the area. Various inputs include text, password, checkbox, and radio. The 'type' attribute determines the input behavior.
9. Essential Attributes
id: Specifies a unique id for an element (cannot be duplicated).
class: Specifies a class name (can be used on multiple elements).
style: Adds inline CSS styling to an element.
title: Adds varied information, often shown as a tooltip.
10. Semantic HTML5
Semantic elements clearly describe their meaning to both the browser and the developer. Using <header>, <nav>, <article>, and <footer> instead of generic <div> tags improves SEO and accessibility.
