XHTML stands for eXtensible HyperText Markup Language. It is markup used to design websites and webpages.
XHTML is much more strict than ordinary HTML, and is based on both XML and HTML. Due to the lax nature of HTML, different web browsers can sometimes display websites incorrectly since there is more than one way to interpret poorly written HTML. The strict and formal nature of XHTML, once fully adopted will allow for web browsers to display the same page correctly between them. Proper XHTML is also easier to read for humans.
