This article is about a web design. For other uses see Rollover (disambiguation) Rollover refers to a button as 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. Rollovers can be done by imagery, text or buttons. The user only requires 2 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.
Coding There are different ways unto creating a rollover, while software and programs as a tool already perpared to make it easier to create a rollover. This is an example of a rollover in CSS and HTML: CSS a a:hover a span HTML Different types of rollovers While rollovers are not in themselves animated images, some users and HTML experts have managed to create animation-like effects.
