Shadow / Drop Shadow
A visual effect that renders a shadow behind images, text, or UI elements to create depth and a floating appearance.
A drop shadow is a visual effect that renders a shadow behind an element, creating the illusion that it floats above the surface. In web design, it is commonly applied to card components and buttons for depth perception, implemented via CSS box-shadow or text-shadow properties.
Shadow parameters include horizontal offset (X), vertical offset (Y), blur radius, and color (typically semi-transparent black). For example, box-shadow: 2px 4px 8px rgba(0,0,0,0.2) produces a subtle shadow shifted 2px right and 4px down with 8px blur.
In image editing, adding shadows to cutout subjects helps them blend naturally with new backgrounds. After isolating a subject with the background removal tool, applying a drop shadow creates a realistic composite. Combining shadows with borders and rounded corners produces polished card designs.
