In computer programming, a rollover is the action of replacing the current content of a graphic with new content when the user mouses over the graphic. This is commonly used for navigation purposes, to create a button that changes state when the user's cursor is over it.
Rollovers can be implemented using HTML and CSS, or using JavaScript. In HTML and CSS, rollovers are implemented using the :hover pseudo-class. When the user mouses over the element, the :hover pseudo-class is applied, and the element's new style is displayed. In JavaScript, rollovers are usually implemented using the onmouseover and onmouseout events. When the user mouses over the element, the onmouseover event is fired, and the element's new content is displayed. When the user mouses out of the element, the onmouseout event is fired, and the element's original content is displayed.
Rollovers are a simple way to add interactivity to a web page. They can be used to create navigation elements that change state when the user's cursor is over them, or to display additional information about an element when the user mouses over it. What is a rollover transfer? A rollover transfer is a type of data transfer in which data is transferred from one location to another, and then the original data is overwritten.

How do rollovers work?
When a user rolls over a element on a page, a rollover is triggered. This rollover can be used to display information or change the appearance of the element. For example, a rollover might change the color of a button when the user mouses over it.
Rollovers are usually coded in JavaScript, and they require two images: one for the initial state of the element, and one for the rollover state. When the user mouses over the element, the rollover image is displayed. When the user mouses out of the element, the initial image is displayed again.
Rollovers can be used for any element on a page, not just images. For example, you could use a rollover to change the color of a text link when the user mouses over it. What is another word for rollover? A rollover is an event that occurs when the user moves the mouse pointer over an object, such as a button, image, or hyperlink. When the mouse pointer is over the object, the object is said to be "rolled over."
