# Banner

> he Banner component is a flexible notification element for showing messages, alerts, or announcements. It supports multiple variants (success, warning, info, premium, etc.), different sizes, optional icons, action buttons, and a closable option. It also includes an autoHide feature to dismiss the banner automatically after a set time and an optional shimmer shade effect for extra visual emphasis.
