Shadow Properties Explained
- X Offset: Moves the shadow horizontally - positive values shift right, negative values shift left
- Y Offset: Moves the shadow vertically - positive values shift down, creating the illusion of depth and elevation
- Blur Radius: Controls how soft or sharp the shadow edge appears - higher values create softer, more diffused shadows while lower values create crisp, defined edges
- Spread Radius: Expands or contracts the shadow size without affecting the element boundaries - positive values make the shadow larger, negative values make it smaller
- Shadow Color: Customize the shadow tint using the color picker - black with varying opacity levels works best for natural-looking depth
- Opacity: Adjust the alpha transparency independently from the color for fine-tuned control over shadow intensity
Design Tips
For realistic material design depth, combine a small offset with moderate blur and low opacity. Multiple box shadows on the same element create layered effects for advanced visual depth. Inset shadows are ideal for pressed button states, recessed card designs, and inner border effects.
