Rollovers and Changing Element Appearances

A rollover in web design is when an element's appearance changes, such as its size, color, background color, decoration, or any property used to style text, typically triggered by a user action like hovering over the element.

In web design, the rollover effect is achieved by applying styles to the 'a' element, and then specifying an alternate style with the 'a:hover' selector for the rollover state.

The order of pseudoclass selectors for the rollover effect to work correctly is :link, :visited, :hover, :active (LVHA), and they must appear in this order in the style sheet.

The examples of rollover effects shown in the text include changing the link color and underlining on rollover, using a fancy bottom border instead of the generic underline, and changing both the foreground and background colors with the addition of a border on rollover.
