Rollover refers to a button created by a web developer or web designer, found within a web page, used to provide interactivity between the user and the page itself. The term rollover in this regard originates from the visual process of "rolling the mouse cursor over the button" causing the button to react (usually visually, by replacing the button's source image with another image), and sometimes resulting in a change in the web page itself. The part of the term 'roll' is probably referring to older mice which had a mechanical assembly consisting of a hard rubber ball housed in the base of the mouse (which rolls) contrary to the modern optical mouse, which has no 'rolling' parts. The term mouseover is probably more appropriate considering current technology.

Rollovers can be done by imagery, text or buttons. The user only requires two images/buttons (with the possible addition of "alt" text to these images) to perform this interactive action. Rollover imagery can be done either by a program with a built-in tool or script coding. The user will have to pick a first image and select an alternate secondary image. A mouse action will have to be set to either "click on" or "mouse over" in order for the rollover to be triggered. Note that when the "mouse over" moves on the image, the alt image/secondary image will appear but won't stay - when the user "mouses out" by moving the mouse away from the image, the original source image will reappear.

Different types of rollovers

While rollovers are not in themselves animated images, some users and HTML experts have managed to create animation-like effects.

  • Zooming rollovers: when the mouse is moved over an image/text or button, it increases its size, depending on the limit size the user sets.
  • Fading rollovers: when the user moves the mouse over an image/text or button, it either fades in or out, depending on the user control.
  • Disjointed rollovers: when the mouse is moved over an image or button, other areas on the screen change to reflect what will happen if the user clicks.
