Introduction to HTML

HTML (Hypertext Markup Language) is the standard programming language for creating web pages and applications. It is the backbone of the World Wide Web and provides the structure and semantic markup for the content that is displayed in web browsers.

Basics of HTML

HTML uses a set of tags to define the structure and content of a web page. Tags are surrounded by angle brackets (< and >), and most tags come in pairs with an opening tag and a closing tag. The content of a tag is placed between the opening and closing tags.

For example, to create a heading, you can use the <h1> to <h6> tags. The number indicates the level of importance, with h1 being the highest and h6 being the lowest. Here's an example:

# This is a heading level 1

## This is a heading level 2

### This is a heading level 3
HTML Elements

HTML elements are building blocks of a web page. They include headings, paragraphs, images, links, lists, tables, forms, and more. Each element has a specific purpose and usage.

Here's an example of creating a paragraph:

<p>This is a paragraph.</p>
Attributes

HTML attributes provide additional information about an element. They are used within the opening tag of an element and are written as a name-value pair. Some common attributes include id, class, src, href, alt, width, height, and many more.

Here's an example of adding an attribute to an element:

<img src="image.jpg" alt="Example Image">
HTML Document Structure

An HTML document follows a specific structure. It starts with the <!DOCTYPE html> declaration, followed by the <html> element which acts as the root of the document. The <head> element contains meta-information about the document, such as the title and references to external stylesheets and scripts. The <body> element contains the visible content of the web page.

Here's an example of a basic HTML structure:

<!DOCTYPE html>
<html>
<head>
  <title>My Web Page</title>
</head>
<body>
  <h1>Welcome to My Web Page</h1>
  <p>This is the content of my web page.</p>
</body>
</html>
Conclusion

HTML is an essential language for web development. It provides the structure and content for web pages, allowing programmers to create visually appealing and interactive websites. Understanding HTML is fundamental for any web developer.
