Red X Icon - Error, Cancel, or Prohibit Symbol for Web and UI Design #268935 (License: Personal Use)

This vector-style red X features smooth, rounded arms against a stark black background, ensuring maximum visibility and contrast. Designed for digital use, it conveys clear negative feedback-such as form validation failure, action cancellation, or restricted access-without ambiguity. Its simplicity supports scalability across responsive layouts and screen readers when paired with proper alt text.

Commonly used in web forms, modals, alert banners, and mobile apps to indicate errors, dismiss actions, or blocked content; matches user intent to understand failure states or exit options quickly.
