Framing (World Wide Web)
From Wikipedia, the free encyclopedia
On a web page, framing means that a website can be organized into frames. Each frame displays a different HTML document. Headers and sidebar menus do not move when the content frame is scrolled up and down. For developers frames can also be convenient. For example, if an item needs to be added to the sidebar menu, only one file needs to be changed, whereas each individual page on a non-frameset website would have to be edited if the sidebar menu appeared on all of them. However, server-side includes and scripting languages such as PHP can also be used to accomplish this aim without some of the drawbacks of frames such as confusing the operation of the address bar and back and forward buttons.
The contents of the frames may be hosted on the same server as the parent page, or it may link in code from another website server such that these external contents are automatically displayed within the frame (transclusion or remote loading). This may be confusing and inconvenient to the users: they can get the impression that the information belongs to the same website; also, less than the full browser window is available and the address bar is less informative. Some websites request not to be used in this way on other websites; some discourage it by including a framekiller script in its pages. The framing website runs a risk of being blamed for external content that, for example, is or becomes inaccurate or objectionable. [1]
Although frames were included in the XHTML 1.0 specification, they were not carried across to XHTML 1.1. The intended eventual replacement is XFrames (XFrames), which attempts to solve the problem of addressing a populated frameset through composite URIs. For those serving web content under the XHTML 1.0 specification, documents may be embedded within one another via either the object or iframe element tags. Under the 1.1 specification, iframe was removed, leaving only the object element for transclusion until browsers begin support for XFrames.
