Whats the difference between HTML and XHTML?

XHTML is actually very similar to HTML. XHTML can be thought of as an XML-compliant version of HTML. The primary differences come to play with syntax and what has been deprecated in XHTML. In short: XHTML is a lot more strict than HTML; validation for XHTML requires cleaner and more proper code than HTML does.

HTML means Hypertext Markup Language, while XHTML means Extensible Hypertext Markup language. HTML is an application of SGML or Standard Generalized Markup language, while XHTML is an application of XML or Extensible Markup Language. Generally both have no major differences but the XHTML is little strict in rules than HTML.

HTML (Hyper Text Markup Language) is the most widely accepted language used to build websites. It is the main structure of a website. It builds tables, creates divisions, gives a heading message (In the title bar of programs), and actually outputs text.

XHTML (eXtensive Hyper Text Markup Language) is the same as HTML, except it has a cleaner syntax. XHTML uses the same tags as HTML, so people who know HTML know messy XHTML. New rules apply in XHTML, such as tags always needing to be ended; Tags need to be "Nested" properly, and such.

DHTML (Dynamic Hyper Text Markup Language) is not a language, but the art of using HTML, JavaScript, and CSS together to create dynamic things, such as navigation menus.

To write standards-based HTML or XHTML, there are a lot of technical details you need to understand that aren't helpful when you're trying to learn the basics of HTML. Our approach is to have you learn the basic concepts of HTML first (without worrying about these details), and then, when you have a solid understanding of HTML, teach you to write standards compliant HTML and XHTML. This has the added benefit that the technical details are more meaningful after you've already learned the basics.

HTML is the means for describing the structure of text information in all web documents. XHTML or Extensible Hyper Text Markup Language is almost similar to HTML in most of its features which is designed for being a HTML successor.

There are very few minor points if we compare them as they are like identical twins. XHTML was actually derived from HTML. The major difference between them is coding in XHTML is comparatively strict than HTML that is if there are some lapses in structure and coding while working in HTML than it could get away easily but that is not a case while working in XHTML. In HTML, there is a liberty to ignore validation of the code. Moreover, tag closing is compulsory in XHTML which is not compulsory in HTML so XHTML closes the tags which were left open by HTML. So we can say that XHTML actually completes HTML.

Also in XHTML, closing of nested tags should be performed in same manner and form in which manner its opening was done. It is also done in HTML but it is not as strict as XHTML. Moreover, tags should be compulsorily used in lowercases in XHTML which is not the case in HTML.

HTML is the Hyper Text Markup Language and is the basic building block for the web pages. The elements of HTML are building blocks for any kind of web pages.

XHTML is an eXtensible HyperText Markup Language and it is a extension of HTML.It contains several features that are useful for creating an effective webpage.

HTML is non dynamic where you can't animate much using scripting language.

HTML is simple coding where no real designs are used whereas XHTML allows us to use many dynamic designs in the script.
