Can you explain the difference between HTML and XHTML?

HTML (Hypertext Markup Language) and XHTML (Extensible Hypertext Markup Language) are both markup languages used for creating web pages. The main difference between the two is that XHTML is a stricter and more well-defined version of HTML.

HTML is a loose and flexible language, which allows for various ways of writing and formatting code. This can make it easier to create a webpage, but can also lead to code that is not properly structured or formatted.

XHTML, on the other hand, is a more formal and structured language. It follows the rules of XML (Extensible Markup Language), which means that all elements must be properly nested and closed, and all attribute values must be in quotation marks. This makes XHTML code more consistent and predictable, but can also make it more difficult to write.

In summary, XHTML is a stricter and more well-defined version of HTML, which enforces stricter rules for coding and formatting.
