Shadows
Shadows help set how elements feel in digital interfaces. They add depth and make items stand out from the background. Modern interfaces use layers, and shadows show how far one surface sits above another. When an element sits higher, its shadow becomes wider and softer. This helps users see which parts are clickable and how the screen is structured.
Shadows also help with quick scanning. Users can spot key items faster when the shadow is clear and consistent.[1] They shape the visual weight of each element, so nothing feels heavier or lighter than it should be. This keeps the layout balanced and easier to read.
Pro Tip: When overused or used improperly, shadows can add visual confusion to a design and hurt its usability.
