INTRODUCTION
This project creates a modern animated button using HTML and CSS. The design focuses on a smooth flip effect that switches between two text layers when the user hovers over it. The background uses soft shadows to give a subtle 3D look that fits well with a neumorphic style. The layout centers the button on the screen so it stands out clearly. The code also includes transitions to make the animation feel smooth and responsive. Overall, it’s a simple interface element that adds a stylish interactive touch to any webpage.
