What type of element is a rollover?

A rollover refers to a visual effect that occurs in response to user interaction, typically when a user hovers their mouse over an element on a webpage. This effect is commonly used in web design to enhance user engagement, providing visual feedback and indicating that an element is interactive, such as a button or a link.

When a rollover is implemented, it may change the appearance of the element, such as altering its color, size, or image, thereby offering a dynamic user experience. This type of interaction aims to guide users through the interface and can improve usability by making it clear which elements are clickable.

Understanding the function of rollovers is important for creating intuitive and visually appealing websites. Other types of elements mentioned in the choices serve different purposes; for instance, structural tags help organize HTML content, whereas grouping methods relate to HTML semantics or design, and roles in SEO are focused on optimizing content for search engines rather than user interaction.
