HTML, also known as HyperText Markup Language, is a language that is specifically designed to be used to generate web pages. These web pages will be showcased on a web browser. One of the main purposes is to structure the information that appears on the page. Some of the information that will be structured by HTML are paragraphs and headings. The grammar foundation for HTML is based off the SGML system. Tim Berners Lee played an important role in the development of HTML. In addition to this, a number of enhancements were also made to the language by the IETF.
Today, HTML has become a global standard that is used around the world. When HTML was first created, the rules for syntax were much more loose than they are today. This allowed it to be used by a larger segment of the population who were not experts at web publishing. Most of the work that was done by web browsers were based on assumptions about the web page. However, standards for HTML were eventually set in place, even though most browsers will still render pages that do not use the proper form of HTML.A newer version of HTML is XHTML, which is a combination of the programming language with XML.
There are a number of entities that are comprised within HTML. Some of these entities are data types, attributes, and elements. When an HTML document is presented, it is important for the author to define which version of HTML they are conforming the document to. To do this, a Document Type Declaration will need to be presented. This will retain code that can be read by machines, and the permitted and prohibited information will be correctly managed. The elements are the most basic foundation of HTML. Elements can be broken down into two categories, and these are content and attributes.
The attributes and content will both have restrictions that the author will need to adhere to is they wish for the document to be validated. The structural markup will explain the purpose of the text. While specific rendering is not taken into consideration, a large number of web browsers have created a standard for elements and the way in which they should be formatted. Another important part of HTML is presentational markup. This will basically define how the text will appear. The purpose of the text is irrelevant with presentational markup. For example, a text that is designated as "bold" within presentational markup will be bold when it appears in the web browser.
Hypertext markup is important as well. This allows certain portions of a document to be linked with different documents. Hypertext markup is basically responsible for the creation of hyperlinks. The attributes that are comprised within an element use what is called name value pairs. The name value pairs will be split by a "=" sign. It is always important to make sure attribute values are quoted. It is not a good habit to leave them unquoted. HTML has played an important role in the creation of the internet.
