XHTML and HTML

The main differences between HTML and XHTML are as follows:
1)      All tags are written in lowercase in XHTML whereas in HTML tags can either be written in uppercase or in lowercase.
2)      Nested tags must be well formed in XHTML whereas in HTML tags can be randomily kept (but it brings various changes in the webpage).
3)      All tag attributes must be quoted in XHML whereas in HTML we can quote or unquote .
4)      All tags must be closed on XHTML (EX ; <hr/><br/>) whereas there is no compulsory in HTML.
Defining XHTML: XHTML stands for Extensible hypertext markup language.
·         XHTML is sticker and clearer version of HTML 4.01
·         XHTML is almost identical to HTML 4.01
·         XHTML is HTML defined as an XML applications.
·         XTML is supported by all major browsers.
XHTML structure: An XHTML document begins with declaration that declares the version of XHTML to which the document conforms . The HTML element allows and contains the head and body. The head contains  information about the documents such as its title and keywords, while body contains the actual content of the document.
Example:
<!DOCTYPE html>
<html>
                <head>
                                <title> My XML title</title>
                </head>
                <body>
                                <h1>Saroj Dahal </h1>
                                <br/>
                </body>

</html>
