Opacity
The transparency level of an element, ranging from 0% (invisible) to 100% (fully opaque). Reduce opacity to create overlays, de-emphasize secondary content, or build layered visual effects. Animate opacity for smooth fade-in and fade-out transitions.
Background
The visual layer behind an element's content, which can include solid colors, gradients, images, videos, or combinations of these. Backgrounds establish visual hierarchy and mood while providing contrast for readable text. Framer supports multiple background layers, allowing you to combine images with color overlays and blend modes for sophisticated effects.
Border Radius
The CSS property that rounds the corners of an element, measured in pixels or percentages. Border radius transforms harsh rectangles into friendlier, more organic shapes—from subtle rounding to perfect circles. Framer provides individual corner controls for asymmetric rounding and variables to maintain consistent corner radii across your design system.
Component
A reusable design element that maintains consistency across your project, from simple buttons to complex navigation systems. Components create a single source of truth—update the main component and all instances reflect the change. In Framer, components can have variants, responsive states, and interactive behaviors.
