Animated Flat Design Warning Icon on Document

This animated icon features a minimalistic document or webpage interface, characterized by a clean white rectangular body with a red header bar and subtle grey lines representing text. A prominent red triangular warning symbol, complete with an exclamation mark, dynamically appears and subtly pulsates over the document, drawing immediate attention. Rendered in a flat design style with solid colors and no gradients, the animation is sharp and clear. This visual element is ideal for digital projects requiring an alert, error message, or notification, seamlessly integrating into interfaces, presentations, or explainer videos to convey important information.
