What is XHTML?

You can attribute much confusion in the computer industry with the vast acronyms used in terminology, so it is logical to ask – what is XHTML?

The contents of this article are great learning resources for developers or a new author of a website or internet documents. Be sure and add it to your library of basic guidelines and simple rules in order to learn to build a website with great accessibility, appropriate doctype, tags and element values that meet the standards for the World Wide Web and display effectively in browsers.

There is much more to building any type of website or software than color, image, font and data. Including an img, form, tag, header, table or interactive element requires a programming code.



XHTML is a relatively new type of web programming language that enables a user to don the best attributes from HTML and XML. While HTML displays data, XML describes the data simplifying validation resulting in support for elimination of undesired events for users.

XHTML stands for extensible hypertext markup language. It is a strict language based on HTML. Javascript can be used with XHTML as a complementary scripting language to create more interactive content. Main examples of javascript are interactive elements that are beyond the capabilities of HTML or XHTML including calculations or an img element that changes when pointed to.

All of the newest internet browsers support XHTML elements. Many web developers make simple mistakes in the validation of an HTML tag in the website header or fail to follow the basic HTML rules and guidelines. XHTML is more strict than HTML so it eliminates these problems making accessibility better for new devices including mobile phones that have difficulty interpreting contents or values in HTML tags that don’t follow the basic HTML rules.
