XHTML vs HTML5
As the name denotes, HTML 5 is the fifth revision of HTML. HTML is a coding language that is used in the development of online scripts. HTML refers to Hyper Text Mark-up Language and is used in the development of web scripts and is one of the earliest languages developed. XHTML on the other hand is a language that is also used in the development of web pages. It stands for Extensible Hyper Text Markup Language and is a hybrid that bridges the gap between HTML 5 and XML. The main function of XHTML is to allow for flexible displays on the net for different devices. XHTML therefore refers to HTML 5 being defined in the scope of an XML application. What differences do these two programming languages offer?
The main function of HTML 5 is to allow for the web browsers to read HTML 5 elements that have been written within tags and convert the content in tags into visual content that the end user can view. The tags are developed on the back end of the site to help in the display of the content of interest. The tags that HTML 5 uses allow for the display of text, images and video to help the display of an amazing web page. XHTML on the other hand is a markup language that extends the scope of HTML 5. This means that HTML language is defined in XHTML as an XML application. The namespaces that XHTML uses correspond to the HTML language.
The first difference that is viewed between XHTML and HTML is that XHTML can be said to be a hybrid language that bridges HTML to XML. HTML5 on the other hand is only the fifth version of the initial HTML 5. Markup representation between XHTML and HTML 5 differ and this is a very special issue that differentiates the tow.
Another difference between the two is that XHTML bears a lot of similarity between it and HTML 4.0 while HTML 5.0 is indeed different from its predecessors and thus not similar in any way to XHTML. When it comes to being strict in following of laid down rules, XHTML is very strict, requiring you to close all tags that have been opened for the tags to work. HTML 5 is less strict and allows for some leeway of error.
HTML is also less strict on restrictions such as nesting tags in already open tags. XHTML strictly specifies which tags can be nested together within tags. Parsing requirements in HTML are borrowed from XML while HTML 5 makes use of its own parsing requirements. XHTML requires one to manually declare a namespace whereas in HTML 5, this requirement is not a necessity.
Type attributes are also needed in XHTML when writing script and type elements. These style attributes are however not needed in HTML 5 in the different script and style elements. XHTML will make use of a long doc type while HTML 5 Makes use of <!DOCTYPE html> . It is also important to note that contrary to optional use of dtd url in XML doctype, HTML does not come with such an option and it is mandatory to use it.
