Difference between HTML XHTML & DHTML
HTML: HTML is a short form of Hyper Text Markup Language. It is a language that is used in creating web apps and websites. HTML is known as a markup language that helps in creating web applications so it is a markup language. The main purpose of HTML is to create web pages or websites which are static in nature. It can only be used in front-end development means it is not used for back-end functionalities like sending or receiving data. Html links are used in connecting one web page to another.
XHTML: XHTML is a short form of Extensible Hyper Text Markup Language. This can be considered as a combined language that uses features from both HTML and XML. All the tags and properties of HTML are inherited in XHTML and it is a bit strict when comes to opening and closing of tags, case sensitivity, and also error finding. It is a good language but it is not very flexible so developers did not show much interest in this language so it is not used as much as HTML for making web pages and websites.
In XHTML you can notice that paragraph tag <p> is closed because without that XHTML will give error but in case of HTML there is no need to close the tag.
DHTML: DHTML is a short form of Dynamic Hyper Text Markup Language. This language was created with the purpose of providing interactivity to the web pages as HTML was only capable of creating static web pages. Users like interactive web pages more than normal web pages, on interactive web pages several features are programmed like changing of style on clicking or hovering. DHTML also make it possible to return a response to the user’s input without the involvement of any web server.
