What is XHTML?

Extensible Hypertext Markup Language, is a markup language used to create web pages.

XHTML files contain code that tells a browser how to structure the page and what elements are part of the content, rather than presentational information such as colors and fonts.

XHTML is a reframed from HTML 4.01, which has been in widespread use since 1999.

Originally released by the W3C in 2000, XHTML 1.0 was later replaced by XHTML 1.1 and then XHTML 1.2 each successive version was an incremental improvement upon the previous one.

The most recent version of XHTML is XHTML5, which is still under development but already supported by many browsers.

XHTML documents must be served with an Internet media type of application. This is done with a MIME type configuration. XHTML 1.0 requires support for UTF-8 encoding.

Many websites today use XHTML as the primary markup language because it simplifies website development, facilitates search engine optimization, and improves accessibility for disabled users.

It provides an alternative syntax to HTML 4 and earlier versions, which helps make content portable between different computing platforms and language

It also provides several facilities that support Web development without using the presentational features of HTML 4 earlier versions.

What is HTML5?

The HTML5 specification is said to be the fifth major version of the Hypertext Markup Language (HTML), the current standard markup language for creating web pages and web applications.

It helps to create websites and web applications. HTML5 provides new features to make web pages more interactive, powerful, and easier to access.

It Uses new elements to define the different parts of our page (header, footer, article).

It Uses new form elements (email, search) and uses microdata attributes to describe the objects on our page with RDFa Lite syntax.

Most of it also gathers data from users through new types of controls (date picker, range slider).

There is no need for third-party plug-ins required to Include video and audio natively on our site (for older browsers). It was released in 2014 and it is still a work in progress.

Despite some limitations, developers are already using it to design games, interactive websites, and even mobile apps.

HTML 5 is intended to subsume not only HTML 4 and XHTML 1, but also XUL, SVG, and MathML.

It includes new features that include New tags and attributes, Canvas API, Video support Geolocation API, Forms API, Web Storage API, Drag and drop support.
