FAQs on XHTML and CSS Tutorial - 2 - Creating our First Webpage Video Lecture - Learn Website Designing with XHTML and CSS - Software Development

1. What is the purpose of XHTML in web development?
Ans. XHTML, or Extensible HyperText Markup Language, is a markup language used for creating webpages. It serves as a stricter and more standardized version of HTML, ensuring that webpages are well-formed and compatible with different browsers. XHTML provides a structure for organizing content, making it easier for search engines to index and for developers to maintain and update websites.
2. How does CSS enhance the appearance of webpages?
Ans. CSS, or Cascading Style Sheets, is a style sheet language used to describe the presentation of a document written in HTML or XHTML. It allows developers to control the layout, colors, fonts, and other visual aspects of a webpage. By separating the content (HTML/XHTML) from its presentation (CSS), CSS makes it easier to create consistent and visually appealing designs across multiple webpages.
3. Can I use CSS without XHTML or HTML?
Ans. No, CSS is designed to work in conjunction with XHTML or HTML. XHTML/HTML provides the structure and content of a webpage, while CSS is responsible for the presentation and styling. Without XHTML or HTML, there would be no content to style using CSS. Therefore, it is necessary to use XHTML/HTML and CSS together to create a complete and functional webpage.
4. Is it necessary to validate XHTML and CSS code?
Ans. While it is not mandatory to validate XHTML and CSS code, it is highly recommended. Validating the code ensures that it follows the standards set by the World Wide Web Consortium (W3C) and helps identify any errors or inconsistencies that may affect the webpage's functionality or appearance. Validating code can also improve the webpage's accessibility, search engine optimization, and compatibility with different browsers and devices.
5. Are there any differences between XHTML and HTML when it comes to web development?
Ans. Yes, there are some differences between XHTML and HTML. XHTML is a stricter and more standardized version of HTML, adhering to XML syntax rules. It requires well-formed code, including properly nested elements and attributes written in lowercase. HTML, on the other hand, is more forgiving and allows for looser syntax. XHTML also offers stricter handling of errors, making it easier to identify and correct mistakes. However, in terms of functionality and basic usage, both XHTML and HTML can be used to create webpages.
