What is XHTML?

XHTML stands for Extensible HyperText Markup Language. Because XHTML incorporates elements of both XML and HTML, it can be regarded as a component of the XML markup language. XML and HTML are both extensions of XHTML. One could say that XHTML is an improvement over HTML.

There is a possibility of missing a closing tag or element case when developing HTML code. Coding is more exacting, polished, and frequently simple thanks to XHTML. The presentation of this data on the web is handled by HTML, while XML is a markup language used to relate, carry, and supply data.

What is HTML5?

The HyperText Markup Language (HTML) is a more recent form, and HTML5 is regarded as an extension of SGML. Web page creation and linkages between them employ HTML5, which makes JavaScript activities possible. On the internet, it is a commonly used markup language.

The older browsers, like IE8 and others, do not support XHTML. HTML5 can use XHTML style tags, but not the other way around. There are a number of limitations that developers must follow when producing XHTML code.
