Key Difference – HTML vs XHTML
What is HTML?
HTML stands for Hyper Text Markup Language. It was the based language of the web. The main objective of HTML is to create the structure of the web page. It is based on SGML. There are different versions of HTML such as HTML 1, 2, etc. The latest version is HTML5. It is majorly used to develop user interfaces are for front-end development. It has many added features. The SVG is used for graphical applications. The Geolocation is used for sharing the location. It also contains native audio and video support.
The HTML language consists of tags. There are separated tags for each task. Each tag is placed between curly braces, and most tags have their corresponding ending tag. The HTML file starts with the Document type declaration. It specifies the HTML version. If the starting tag is <html>, then the closing tag is </html>. There are two sections in the HTML document. The <head> section provides the details of the document such as title etc. All the tags that build the structure of the web page is inside the <body> section. The paragraphs, headings, tables, lists etc. are in that section.
What is XHTML?
There are many versions of HTML. The HTML 4 requires more computing power to take average HTML page and render it in a coherent and consistent manner. Therefore, the XHTML was introduced. XHTML stands for Extensible Hyper Text Markup Language. XHTML is not extensible. It is based on XML. The XML is similar to HTML, but it is designed to describe data. Unlike the HTML tags, the XML tags are not predefined. Therefore, the programmer can write the tags according to the application.
The main objective of developing XHTML was to develop to help the programmer to transfer from HTML to XML. XHTML is a descriptive markup language which works similar to HTML while handling data organization well. The first document type in the XHTML family is XHTML 1.0. XHTML is more similar to HTML 4.01. It sticker than HTML. It provides more precise standards and specifications for the website to understand data and to transmit them.
All the XHTML documents should start with the documents declaration at the top. All the attributes and the tag names should be in simple letters. It is necessary to nest all the tags properly. The attribute values are included inside quotes. Those are few facts to consider when writing XHTML files.
Overall, the XHTML is useful to make the web pages more likely to be compatible with present and future web browsers and to render accurately. XHTML makes easier to maintain and format for a long period of time. Even though the XHTML provides more precise standards to understand the data; one drawback is that it is harder to debug.
What is the Similarity Between HTML and XHTML?
- Both are markup languages designed for web development.

Summary – HTML vs XHTML
HTML and XHTML are two markup languages. Hypertext Markup Language (HTML) is the standard markup language for creating web pages and web applications. Extensible Hypertext Markup Language (XHTML) is a part of the family XML markup languages that mirrors the versions of HTML. The key difference between HTML and XHML is that, HTML is based on SGML while XHTML is based on XML.
