Why We Added 3D Depth to a 2D Game

Faking the Third Dimension

Creating the illusion of depth in a purely 2D DOM environment requires a lot of CSS trickery. In Cards Match, the 'thickness' of the tiles is actually achieved using precise `box-shadow` layering and `transform: translateY` animations.

This pseudo-3D effect isn't just for looks; it serves a crucial gameplay purpose. The drop shadows help players instantly understand the visual hierarchy of the stack. You intuitively know which tile is on top because your brain interprets the shadows as physical height. It's a perfect example of design serving function.
