GraniteAlert is a container for other components, which are rendered inside the alert, and can be used as a way of displaying a global notification. The property level maps to the level attribute of granite-alert, with each level (info, warning, error and success) providing a different style. The property compact enables additional style rules that reduce spacing around the content. It is also posible to injecting styles directly into the granite-alert shadow DOM, by using style modules ([see examples](https://vaadin.com/directory/component/granite-alert/samples))
