XHTML: The Stricter, More Compatible Version of HTML

XHTML stands for Extensible Hypertext Markup Language. It's a markup language used to create web pages and is a stricter version of HTML (Hypertext Markup Language). XHTML is designed to be more compatible with XML (Extensible Markup Language) and is based on the same syntax as HTML, with some additional rules and requirements. XHTML documents must be well-formed and follow strict syntax rules, which makes them easier to parse and process by web browsers and other software. XHTML is also more accessible and search engine-friendly than HTML, making it a popular choice for modern web development.
