| Description | XHTML ((Extensible Hypertext Markup Language) is a reformulation of HTML as an XML-based markup language. It combines the flexibility of XML with the familiar syntax and structure of HTML. XHTML documents adhere to strict XML syntax rules, requiring elements to be properly nested and closed. This ensures greater consistency and compatibility across different web browsers and devices. XHTML is commonly used for creating web pages and applications, offering features such as support for multimedia content, forms, and styling through CSS (Cascading Style Sheets). It is an important standard in web development, facilitating the creation of accessible, well-structured, and interoperable web content. |
| Technical details | XHTML documents are written in XML syntax, which means they must adhere to strict rules for structure and syntax. |
