Responsive Website Design
EXtensible HyperText Markup Language is a stricter, more XML-based version of HTML and is defined as an XML application and supported by all major browsers. XHTML was developed by World Wide Web Consortium (W3C) to help web developers make the transition from HTML to XML. By migrating to XHTML today, Web developers can enter the XML world with all of its benefits, while still remaining confident in the backward and future compatibility of the content.
EXtensible HyperText Markup Language (XHTML) is a markup language where all documents must be correctly formatted. XHTML was developed to make HTML more extensible and flexible to work with other data formats such as XML (EXtensible Markup Language). XHTML comes with a much stricter error handling to solve the problem when browsers ignore errors in HTML pages, and try to display the website even if it has some errors in the markup.
