Overview of HTML Structure
An HTML document is structured using a combination of tags, attributes, and content. The basic structure includes:
- Document Type Declaration (DOCTYPE): Defines the version of HTML being used and ensures compatibility with web browsers. It's typically the first line of an HTML document.
- HTML Element (<html>): The root element that contains all other elements in the document. It includes attributes such as lang for specifying the language used in the document.
- Head Section (<head>): Contains metadata, such as the document title, character encoding, viewport settings, stylesheets, scripts, and other information that is not directly displayed on the web page.
- Body Section (<body>): Contains the visible content of the web page, including text, images, links, forms, and other elements that users interact with.
Example of an HTML Document
Let's create a simple example of an HTML document to understand its structure:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My First HTML Page</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<header>

- HTML Element (<html lang="en">): The root element of the document, specifying the language as English (en).
- Head Section (<head>):
- <meta charset="UTF-8">: Defines the character encoding as UTF-8.
- <meta name="viewport" content="width=device-width, initial-scale=1.0">: Sets the viewport width and initial scale for responsive design.
- <title>: Sets the title of the webpage.
- <link rel="stylesheet" href="styles.css">: Links an external stylesheet for styling.
- Body Section (<body>): Contains the visible content of the webpage, structured into:
- <header>: Includes the website's header with a navigation menu (<nav>).
- <main>: Holds the main content sections (<section>).
- <footer>: Contains copyright information.
- Content Sections (<section>): Divided into "Home," "About," "Services," and "Contact" sections, each with specific content and elements like headings, paragraphs, lists, and forms.

Explanation of HTML Structure Elements
- DOCTYPE (<!DOCTYPE html>): Informs the browser that the document is an HTML5 document, ensuring modern standards compliance.
- HTML Element (<html>): Acts as the root element, encapsulating the entire document and specifying the document's language (lang attribute).
- Head Section (<head>): Contains metadata (<meta> tags) for character encoding, viewport settings, title, and external resources (e.g., stylesheets, scripts).
- Body Section (<body>): Contains the visible content of the webpage, including headers, main content (<main>), footer, and any interactive elements like forms or scripts.
- Semantic Elements (<header>, <nav>, <main>, <section>, <footer>): Enhance the document's structure and accessibility by providing semantic meaning to different sections of content.
- Content Sections (<section>): Organize content logically, each identified by a unique id attribute for linking and styling purposes.
- Form Element (<form>): Allows users to input and submit data, utilizing various input types (<input>, <textarea>) and attributes (action, method) for form handling.
- Script Element (<script>): Links external JavaScript files for dynamic behavior and interactivity within the webpage.
