Elements

A web page, as an information set, can contain numerous types of information, which is able to be seen, heard or interact by the end user:

Perceived (rendered) information:
  • Textual information: with diverse render variations.
  • Non-textual information:
    • Static images may be raster graphics, typically GIF, JPEG or PNG; or vector formats such as SVG or Flash.
    • Animated images typically Animated GIF and SVG, but also may be Flash, Shockwave, or Java applet.
    • Audio, typically MP3, ogg or various proprietary formats.
    • Video, WMV (Windows), RM (RealMedia), FLV (Flash Video), MPG, MOV (QuickTime)
  • Interactive information: see interactive media.
    • For "on page" interaction:
      • Interactive text: see DHTML.
      • Interactive illustrations: ranging from "click to play" images to games, typically using script orchestration, Flash, Java applets, SVG, or Shockwave.
      • Buttons: forms providing alternative interface, typically for use with script orchestration and DHTML.
    • For "between pages" interaction:
      • Hyperlinks: standard "change page" reactivity.
      • Forms: providing more interaction with the server and server-side databases.
Internal (hidden) information:
  • Comments
  • Linked Files through Hyperlink (Like DOC,XLS,PDF,etc).
  • Metadata with semantic meta-information, Charset information, Document Type Definition (DTD), etc.
  • Diagramation and style information: information about rendered items (like image size attributes) and visual specifications, as Cascading Style Sheets (CSS).
  • Scripts, usually JavaScript, complement interactivity and functionality.
Note: on server-side the web page may also have "Processing Instruction Information Items".

The web page can also contain dynamically adapted information elements, dependent upon the rendering browser or end-user location (through the use of IP address tracking and/or "cookie" information). From a more general/wide point of view, some information (grouped) elements, like a navigation bar, are uniform for all website pages, like a standard. These kind of "website standard information" are supplied by technologies like web template systems.

Famous quotes containing the word elements:

    “The Laws of Nature are just, but terrible. There is no weak mercy in them. Cause and consequence are inseparable and inevitable. The elements have no forbearance. The fire burns, the water drowns, the air consumes, the earth buries. And perhaps it would be well for our race if the punishment of crimes against the Laws of Man were as inevitable as the punishment of crimes against the Laws of Nature—were Man as unerring in his judgments as Nature.”
    —Henry Wadsworth Longfellow (1807–1882)

    “Barbarisation may be defined as a cultural process whereby an attained condition of high value is gradually overrun and superseded by elements of lower quality.”
    —Johan Huizinga (1872–1945)

    “Our institutions have a potent digestion, and may in time convert and assimilate to good all elements thrown in, however originally alien.”
    —Herman Melville (1819–1891)
