1. What is HTML?
HTML stands for HyperText Markup Language. It is the standard markup language used to create web pages. HTML uses tags to structure the content and elements on a webpage.
2. What are the different versions of HTML?
There have been several versions of HTML, including HTML 4, XHTML, and the latest version, HTML5. HTML5 introduced new features like video, audio, and canvas elements, as well as improved semantics and accessibility.
3. What is the difference between HTML and HTML5?
HTML5 is the latest version of HTML and comes with several new features and improvements. Some of the key differences include the addition of new semantic elements, support for multimedia elements without plugins, and improved form validation.
4. What are semantic elements in HTML?
Semantic elements in HTML are tags that give meaning to the structure of a webpage. They help search engines and assistive technologies understand the content better. Examples of semantic elements include <header>, <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.
6. How do you include CSS styles in an HTML document?
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.
7. What is the difference between inline and block-level elements?
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 <a>. Block-level elements, on the other hand, start on a new line and take up the full width available. Examples of block-level elements include <div> and <p>.
8. What is the purpose of the doctype declaration in HTML?
The doctype declaration is used to specify the version of HTML or XHTML used in a document. It helps the browser understand how to interpret the markup and render the webpage correctly.
9. What is the difference between GET and POST methods in HTML forms?
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> tag. The href attribute specifies the URL of the page you want to link to. For example, <a href='https://www.example.com'>Link</a> creates a hyperlink to https://www.example.com.
