Is XHTML still used?

The terms HTML, HTML5 and XHTML are frequently used in web design.

What is XHTML and HTML5?

XHTML is a combination of HTML and XML, while HTML5 is a version of HTML. XHTML has its own parsing requirements, while HTML does not have any specific requirements and uses its own.

Why use XHTML instead of HTML?

XHTML was developed to make HTML more extensible and flexible to work with other data formats (such as XML). In addition, browsers ignore errors in HTML pages, and try to display the website even if it has some errors in the markup. So XHTML comes with a much stricter error handling.

Does HTML5 use CSS3?

Both include features for playing audio and video within web pages, and for using Scalable Vector Graphics. However, HTML5 on its own cannot be used for animation or interactivity – it must be supplemented with CSS3 or JavaScript.
