Close Icon - Universal Symbol for Cancel, Dismiss, or Error Actions #3606645 (License: Personal Use)

This minimalist icon features a bold black 'X' centered within a white circular field, all enclosed by a black rounded-square container. The design follows modern UI/UX conventions with strong contrast and geometric simplicity for maximum legibility across devices and sizes. It is widely adopted in web and mobile interfaces to represent dismissal, cancellation, or error states.

Commonly used in user interfaces as a close button on modals, pop-ups, notifications, or form fields; also appears in error messages and accessibility tools to indicate failure or rejection. Matches user intent to dismiss, undo, or exit an action.
