Layer Multiple Shadows for Realistic Depth
A single box-shadow looks flat. Layer multiple shadows with increasing blur and decreasing opacity to mimic real light.
Incorrect (single flat shadow):
.card {
box-shadow: 0 4px 16px rgba(0, 0, 0, 0.2);
}Correct (layered shadows):
.card {
box-shadow:
0 1px 2px rgba(0, 0, 0, 0.06),
0 4px 8px rgba(0, 0, 0, 0.04),
0 12px 24px rgba(0, 0, 0, 0.03);
