Differences Between HTML vs XHTML
HTML full form is Hyper Text Markup Language. HTML was earlier proposed by Tim Berners Lee and developed by W3C and WHATWG and released in the year 1993. HTML has been extended from SGML. The filename extension of HTML is .html and .htm. The last release of HTML is HTML5, which is a major release for HTML in the year 2014.
HTML is used for developing web pages and applications. HTML can be embedded with CSS (Cascading style sheet) and Java Script. HTML consists of elements, these elements define the structure of HTML pages. HTML elements are used to represent heading, paragraph, images, tables and many more features. HTML elements are enclosed in HTML tags like <H1></H1>. The browser does not display HTML tags; it displays only the content enclosed in tags.
HTML pages can be developed using the HTML editors like Notepad (in Windows machine) and Text edit (in Mac Book or Mac Machine). The basic HTML page structure consists of 1. Doctype tag like <!DOC TYPE html>, which describes the HTML version written. 2. HTML Root Element tag like <html></html>, which is having all the code written for web page. 3. Head element tag like <h1></h1>, in this title and heading is described. 4. Body element tag like <body></body>, it holds the content of the document.
XHTML full form is Extensible Hyper Text Markup Language. XHTML was developed by World Wide Web Consortium and it was released in the year 2000. It has been extended from XML and HTML. The filename extension of XHTML is .xhtml and .xht. The last release of XHTML is XHTML5, which is being developed as XML configured with HTML5 specifications.
The main idea behind developing XHTML to extend HTML language and can be used for all the data formats using XML format. XHTML has a feature of error handling, which is handling the technical error thrown by the web pages and applications in HTML.
XHTML developed pages can be used in existing browsers or in new browsers as well and they can be easily viewed, edited and validated with help of XML tools. It is compatible with all the browsers and can be easily embedded with scripts and applets based on HTML and XML document object model. It is very fast, accurate, easily maintained, editable, convertible and formatted. XHTML always provides the consistent and well-defined structure format for web pages that can be easily processed by web browsers.
XHTML syntax is almost same as HTML syntax. XHTML structure is also similar to HTML only but XHTML is case sensitive and attributes are added, changed and cannot be shortened. In XHTML, it should follow the proper structure and tags should be properly nested.
