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.
- For "on page" interaction:
- 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:
“psychologist
It is through friendships that teenagers learn to take responsibility, provide support, and give their loyalty to non- family members. It is also in teenage friendships that young people find confidants with whom to share thoughts and feelings that they are not comfortable sharing with their parents. Such sharing becomes one of the elements of true intimacy, which will be established later.”
—David Elkind (20th century)
“In spite of all their kind some elements of worth
With difficulty persist here and there on earth.”
—Hugh MacDiarmid (18921978)
“Three elements go to make up an idea. The first is its intrinsic quality as a feeling. The second is the energy with which it affects other ideas, an energy which is infinite in the here-and-nowness of immediate sensation, finite and relative in the recency of the past. The third element is the tendency of an idea to bring along other ideas with it.”
—Charles Sanders Peirce (18391914)
