Hello people,
While surfing the net i came across the word 'Mouseover'. I know it is something related to mouse. But don't know exactly. Can anybody explain it and what's the use of it?

It is a common instruction for the operator to move the mouse so that the cursor on the screen, usually a little arrow, passes over a certain part of the screen which automatically triggers some sort of action, for an example, open a document.
Look on the page for text of a different color or text that's underlined.

Technically, mouseover is JavaScript element that triggers a change on an item (typically a graphic change, such as making an image or hyperlink appear ) in a Web page when the pointer passes over it. The change usually signifies that the item is a link to related or additional information. Mouseovers are widely used in Navigation Bars, pop-up windows, and/or form submissions.

Mouseovers require JavaScript in two places of an HTML document. At the beginning of your document and before the BODY tag, JavaScript defines the event to take place. After the BODY tag, HTML code contains the actual mouseover element in the place on your Web page you want the action to take place. When your mouse passes over the HTML code containing the mouseover element, it signals the JavaScript event to take place.

Mouseovers are most commonly used in navigation, causing an image or text to change when the mouse is placed over the image or text. Most often this is a color change, but you can also change the entire image. In your WebSite Complete project, you must preview your site in order to see any mouseover effects.
