HTML

HTML (HyperText Markup Language) is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.

HTML is the foundational technology for creating web pages. It provides the structure, while CSS adds styling, and JavaScript adds interactivity. Understanding HTML is essential for anyone working in web development, as it's the starting point for creating web content.

Whether you're a beginner or an experienced developer, mastering HTML is crucial for building and maintaining websites, and it serves as the gateway to more advanced web technologies.

1. Overview of HTML

HTML is not a programming language; it's a markup language that describes the structure of web pages. It uses various tags and attributes to define the content and layout.

2. Basic Structure of an HTML Document

An HTML document is structured with a series of elements and tags. Here's a basic example:

<!DOCTYPE html>
<html>
  <head>
    <title>My Page</title>
  </head>
  <body>
    <h1>Welcome to My Website</h1>
    <p>This is a paragraph.</p>
  </body>
</html>

3. Key Elements of HTML

Tags: HTML uses tags to define elements. Tags are enclosed in angle brackets, like <tagname>.
Attributes: Attributes provide additional information about an element and are placed within the opening tag, like <tagname attribute="value">.
Elements: An element is a complete set of opening and closing tags, including the content between them.

4. Common HTML Tags

Headings: <h1>, <h2>, <h3>, etc.
Paragraph: <p>
Links: <a href="URL">
Images: <img src="image.jpg">
Lists: <ul>, <ol>, <li>

5. HTML Forms

HTML forms are used to collect user input. Here's an example:

<form action="/submit" method="post">
  <label for="name">Name:</label>
  <input type="text" id="name" name="name" required>
  <input type="submit" value="Submit">
</form>
