HTML is an extremely well-known computer programming language currently in use by website designers to come up with sites and also complete sites can be produced making use of html by itself.
HTML is short for Hypertext Markup Language and it has been widely used essentially since the start of the world wide web,
nonetheless as the internet has changed, several common html practices have also changed.
One example is, using tables to structure a webpage was really common in the beginning of the world wide web however as web browsers evolved and technologies improved, different methods just like CSS emerged to enable site designers to create websites which may be displayed in the same manner across different browsers (browser compatibility) and in many cases the same internet browsers but different editions (version compatibility).
A further development came with the development XHTML, an abbreviation for Extensibe Hypertext Markup Language, a newer, more versatile version of HTML.
XHTML is part of the family of XML languages though it may be also a part of HTML, or even more closely relevant to html version 5.0, it's designed to perform far more robustly with xml dependent user agents along with properties.
XHTML may also be referred to as an application of XML because it's actually a more prohibitive subset of SGML, this means that compared with html, you can actually parse xhtml documents using a common xml tool, such as an xml parser. The only necessity is that the xhtml document will have to be well formed since there are specified xml rules to go by, however with html, you simply can't parse it unless you're working with a much more lenient, html specific parser.
The principle distinction concerning xml and html is that xml is a markup language, so there are zero semantics involved and no rules as to just what exactly can and cannot be incorporated, xml purely describes the data. Html however has semantic meaning and determines how data and text is expected to be viewed.
For example, in html, you can exclusively apply the head tag to explain the header components, where as all body elements have to be included inside of the body tag, to also include a paragraph you have to contain it within a paragraph tag, this is just what is meant by the word semantics.
XML as, I have just pointed out, has zero semantic tags or predetermined classifications, for example in an xml document your tags will be able to hold any meaning and any data, you generate your own tags.
Due to all these key differences, xml, unlike html, is not really something that you can see with the naked eye on any website, rather it is placed in the background, or the source code of the web site, as websites grew to be more dynamic entities, and also the need to consume this data originated via totally different platforms, from tablets, to PCs to smart phones, XML grew to become more and more necessary to insuring that this information was ordered, stored and transferred in a constant and universal method.
Xhtml accomplished an very important goal and had been created for a number of reasons. The major good reason was to fix the compatibility hole involving a client computer and a website on a server, a language was needed that could transport and present the meaning of data on a web page to a personal computer, xhtml filled this need.
The next reason was in order to meet the gap for a standard language format which could easily be properly translated over different internet browsers and platforms as well as on different screen types, again xhtml fulfilled this specific want beautifully.
With the range of numerous devices, from smart phones, PCs, laptops, tablets, not to mention distinctive internet browsers from Internet Explorer to Mozilla, and editions from IE7 to IE8, it is rather vital for any would be web designer to move from html to xhtml development to allow your websites to display effectively throughout all programs and browsers.
