HTML is a markup language used to develop web pages and web apps.
HTML elements are enclosed in tags which cannot be displayed on the web page when rendered but its content is displayed on the browser.
You can develop HTML pages using text editors like notepad in windows and text edit in Mac OS.
There are other third-party editors that you can use as well like sublime text, brackets, etc. File extension in HTML is
The basic skeleton structure of an HTML page is as follows:
<!DOCTYPE html> <html> <head> <title> Title</title> </head> <body> <h1> Heading</h1> <p> Paragraph.</p> </body> </html>
XHTML being an extensible text markup language was developed by w3c and released in the year 2000. Its file extension is
The latest release version is xHTML5 which is XML with HTML5 configurations. The main reason behind the development of XHTML was to extend HTML language so that it could be used for all data formats by the use of XML.
In addition, XHTML has error handling features for handling technical errors thrown by web pages in HTML
XHTML pages can support existing browsers and new browsers as well and it can be edited, viewed, and validated with XML tools.
Its compatibility with all browsers makes it easy to embed scripts and applets based on XML and HTML DOM.
Its most important features are convertibility, editability, accuracy, and maintainability.
It always provides a consistent formatting and well-defined structure for web pages.
XHTML syntax is almost similar to the HTML, even the structure is similar but XHTML is case sensitive and with additional attributes which can be changed but not shortened, in XHTML proper structures should be followed and proper nesting of elements is vital.
The following table draws the comparisons between XHTML and HTML5
|It uses an extensive hypertext markup language||It uses a hypertext markup language|
|xHTML is always case sensitive||HTML is case insensitive|
|Its internet media type is application/xHTML + XML||Its internet media type is text/html|
|xHTML is a lot more expressive as compared to HTML||HTML is less expressive|
|xHTML is an application of XML||HTML is an application of SGML|
|XHTML has its markup language as the format type||HTML has a document file format|
|It parses with a standard XML parser||Require lenient parser specific for HTML|
|It is concerned with well-formed constraints||HTML is less concerned with well-formed constraints|
There are changes that you need to apply to functions to make XHTML be case sensitive.
HTML and XHTML are widely used by established web developers and IT institutions to develop web applications and web pages and it supports server-side scripting with other assisting languages embedded on.
In conclusion, it would be easy to learn XHTML if you already perfect in HTML because they are closely related to each other, a few concepts you need to figure out and you are good to fly. They are both easy to learn and understand and form a basis for all other web development frameworks.
