Web page creation by any method requires a working knowledge of Hypertext Markup Language (HTML). It is the standard markup language on the Web, and in other settings. HTML is standardized by an organization called the World Wide Web Consortium (W3C). You can learn more about the W3C at www.w3.org.
Cascading Style Sheets (CSS) are rules in an external text file that determine how to display HTML elements in your Web pages. CSS contain formatting instructions that can define the font, color and phrase elements used on a particular markup page.
Cloud computing has also impacted Web design. Cloud computing is software services that are provided over the Internet, rather than at a company site. For instance, in the past, companies had to have a server room with Web, e-mail, file and database servers.

Graphical user interface (GUI) markup editor applications place markup instructions into files for you; you do not need to know HTML to use GUI editors. Many GUI HTML editors still do not produce valid HTML. Nevertheless, such editors provide a graphical user interface that makes it easy for you to create HTML pages without writing any code manually.
Standard Generalized Markup Language (SGML) is a metalanguage, which means that it is used to create other languages, including HTML and XHTML. SGML was originally created by IBM and was standardized in 1986 by the International Organization for Standardization (ISO). SGML is a powerful markup language that describes documents by organizing concepts separately from their visual presentation. However, it is also very complex and difficult to learn.
