Specification: HTML Basics and Tags

Introduction to HTML

HTML (Hypertext Markup Language) is the standard markup language for creating web pages. It provides the structure and content of a webpage by using different tags. This specification aims to provide a comprehensive overview of the basic HTML tags and their usage.

Commonly Used HTML Tags

1. `<html>`

The <html> tag is the root element of an HTML page. It defines the document type and sets the language of the webpage.

2. `<head>`

The <head> tag contains meta-information about the HTML document. It typically includes the title of the page, references to external stylesheets, scripts, and other metadata.

3. `<body>`

The <body> tag represents the content of an HTML document. It contains all the visible elements such as text, images, links, and more.

4. `<h1>` to `<h6>`

The <h1> to <h6> tags are used for headings on a webpage. <h1> represents the most important heading, while <h6> represents the least important heading.

5. `<p>`

The <p> tag is used to define a paragraph. It is commonly used to structure the text content of a webpage into paragraphs.

6. `<a>`

The <a> tag is used to create a hyperlink. It can be used to link to other web pages, files, sections within a page, or email addresses.

7. `<img>`

The <img> tag is used to insert an image into an HTML document. It requires the \"src\" attribute to specify the image source (URL or file path).

8. `<ul>` and `<li>`

The <ul> tag represents an unordered list, while the <li> tag represents a list item. It is commonly used to create bulleted lists on a webpage.

9. `<table>`, `<tr>`, `<th>`, and `<td>`

These tags are used to create tables in HTML. The <table> tag represents the table itself, <tr> represents a table row, <th> represents a table header cell, and <td> represents a table data cell.
