1. What is HTML, and why is it important for web development?

Answer: HTML, or Hypertext Markup Language, is a standard markup language used to create the structure of web pages. It provides a set of elements and tags that define the various components of a webpage, such as headings, paragraphs, links, and images. HTML is fundamental to web development because it serves as the backbone for creating content on the internet. It works in conjunction with CSS (Cascading Style Sheets) and JavaScript to build visually appealing and interactive websites.

2. How do I create a hyperlink in HTML?

Answer: To create a hyperlink in HTML, you use the <a> (anchor) tag. Here’s a basic example:
<a href="" target="_blank" title="Visit Example">Visit Example</a>
In this example, the href attribute specifies the URL the link points to. The target="_blank" attribute opens the link in a new browser tab or window, and the title attribute provides additional information when the user hovers over the link

3. What is the purpose of the HTML meta tag?

Answer: The <meta> tag in HTML is used to provide metadata about the document, such as character set, viewport settings, and description. For example:
<meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0">
In this snippet, the first <meta> tag sets the character set to UTF-8, ensuring proper text encoding. The second <meta> tag configures the viewport for responsive design on various devices.

4. How do I embed an image in an HTML document?

Answer: To embed an image in HTML, you use the <img> tag. Here’s a simple example:
<img src="image.jpg" alt="Description">
The src attribute specifies the image file’s source (URL or file path), and the alt attribute provides alternative text for accessibility and in case the image cannot be loaded.

5. What is the difference between HTML and HTML5?

Answer: HTML5 is the latest version of HTML, introducing new features and improvements over its predecessors. Some key differences include:
Semantics: HTML5 introduces new semantic elements like <article>, <section>, <nav>, and <header>, making it easier to structure content.
Multimedia: HTML5 includes native support for audio and video playback without the need for third-party plugins, using the <audio> and <video> elements.
Form Enhancements: New input types (e.g., <input type="date">) and attributes (e.g., required, pattern) provide better form validation and user experience.
Canvas and SVG: HTML5 includes the <canvas> element for drawing graphics dynamically and supports Scalable Vector Graphics (SVG) for resolution-independent graphics.
