Flat Design Document Icon with Animated Loading Progress Bar

This animation features a clean, minimalist document icon in a flat design style. The rectangular icon, outlined in black, includes horizontal lines that simulate text or data. A vibrant turquoise color animates smoothly from left to right, filling these lines to create a dynamic loading or progress bar effect. Below the main icon, a small circular element simultaneously fills with the same turquoise hue, reinforcing the sense of completion or advancement. This simple yet effective animation is perfect for indicating data processing, task completion, certification, or any concept requiring a clear visual cue of progress. Its modern aesthetic and crisp lines make it a versatile asset for corporate presentations, technology-focused videos, or user interface demonstrations, adding a professional touch without distraction.
