HTML, or HyperText Markup Language, is the standard markup language used to create and design documents on the World Wide Web. It's a fundamental building block for creating web pages and web applications. HTML provides a set of elements or tags that structure the content on a web page, such as headings, paragraphs, links, images, lists, and more.
Here's a basic example of HTML:
```html
<!DOCTYPE html>
<html>
<head>
<title>My First Web Page</title>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is a paragraph of text.</p>
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
<a href="https://www.example.com">Visit Example.com</a>
</body>
</html>
```
Let's break it down:
- `<!DOCTYPE html>`: This declaration specifies the HTML version being used (in this case, HTML5).
- `<html>`: This is the root element of the HTML document.
- `<head>`: Contains meta-information about the HTML document, such as the title.
- `<title>`: Sets the title of the HTML document, which appears in the browser's title bar or tab.
- `<body>`: Contains the content of the HTML document, such as text, images, links, etc.
- `<h1>`, `<p>`, `<ul>`, `<li>`, `<a>`: These are various HTML elements or tags used to structure and define content. For example, `<h1>` represents a top-level heading, `<p>` represents a paragraph, `<ul>` and `<li>` are used for unordered lists, and `<a>` creates a hyperlink.
HTML is often combined with CSS (Cascading Style Sheets) and JavaScript to enhance the presentation and functionality of web pages. CSS is used for styling (colors, fonts, layout), and JavaScript is used for interactivity and dynamic content. Together, HTML, CSS, and JavaScript form the core technologies for building websites and web applications.
