El ícono de cerrar en bootstrap es una utilidad que se usa para descartar cualquier contenido (por ejemplo, Alertas, Modales, Popovers). Está representado por un icono genérico de cruz/cerrar.
A continuación se muestra un código HTML de muestra que incluye un icono de cierre para descartar contenido en el arranque:
html

Nota: El atributo de descarte de datos se puede usar con una etiqueta de botón para apuntar al componente a descartar, como un modal o una alerta.
