:::demo Alert allows you to configure if it's closable. The close button text and closing callbacks are also customizable. `closable` attribute decides if the component can be closed or not. It accepts `boolean`, and the default is `true`. You can set `close-text` attribute to replace the default cross symbol as the close button. Be careful that `close-text` must be a string. `close` event fires when the component is closed.
