HTML for Beginners: Essential Guide

HTML (HyperText Markup Language) is the standard language used to create web pages. It consists of a series of elements (tags) used to structure content on a webpage. Below is a comprehensive guide with commonly used HTML tags, their descriptions, and examples.

Basic Structure of HTML:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>HTML Example</title>
</head>
<body>

</body>
</html>

Explanation:

<!DOCTYPE html>: Defines the document type (HTML5).
<html>: Root element of an HTML page.
<head>: Contains metadata (title, meta tags).
<meta>: Provides metadata like character set and viewport settings.
<title>: Sets the title of the page.
<body>: Contains the visible content.

Headings:

HTML provides six levels of headings, <h1> being the highest and <h6> the lowest.

<h1>This is an H1 Heading</h1>
<h2>This is an H2 Heading</h2>
<h3>This is an H3 Heading</h3>

Paragraphs:

  <datalist id="languages">
    <option value="JavaScript">
    <option value="Python">
  </datalist>

form: Associates the input element with a specific form (useful when the input is outside of the form).

<html lang="en">
