, <main>
, <article>
, and <footer>
.
5. What is the purpose of the alt attribute in an image tag?
The alt attribute in an image tag is used to provide alternative text for an image. It is displayed if the image fails to load or if the user is using a screen reader. The alt text should describe the content of the image accurately.

You can include CSS styles in an HTML document using the <link>
tag to link an external CSS file or by using the <style>
tag to define inline styles directly in the HTML document.

Inline elements do not start on a new line and only take up as much width as necessary. Examples of inline elements include <span>

and <p>

The GET method is used to retrieve data from a server, while the POST method is used to send data to a server for processing. The data sent using the GET method is visible in the URL, while the data sent using the POST method is not.
10. How do you create a hyperlink in HTML?
You can create a hyperlink in HTML using the <a>
