A CSS effect that applies visual filters like blur or color adjustment to the area behind an element, creating frosted glass or tinted overlay effects. This technique is popular for navigation bars and modal backgrounds that need to stand out while maintaining context with underlying content. In Framer, apply backdrop filters through the Fill properties to create modern, layered interfaces.

A CSS effect that adds shadow beneath or around an element, creating depth and visual separation from the background. Shadows help establish hierarchy by making elements appear to float above the page surface. Framer offers detailed shadow controls including multiple shadows, inner shadows, and variables for consistent elevation systems.

The difference in luminance between foreground and background colors, critical for text readability and accessibility. WCAG guidelines require minimum contrast ratios of 4.5:1 for normal text and 3:1 for large text. Use contrast checking tools to ensure your color combinations are accessible to users with visual impairments. See Understanding contrast ratio.

A parent element that holds and organizes child elements, defining boundaries for layout and positioning. Containers with maximum widths prevent content from becoming too wide on large screens while allowing full-width backgrounds. Framer's containers support auto layout, padding, and responsive size controls for flexible layouts.

A gradual transition between two or more colors, creating depth, dimension, and visual interest. Gradients add sophistication to backgrounds, buttons, and text without requiring images. Framer supports linear, radial, and angular gradients with multiple color stops and precise positioning.

A grainy texture effect added to backgrounds or elements for visual interest and tactile quality. Subtle noise can add depth and sophistication, reducing the flatness of solid colors. Apply noise sparingly—heavy noise can look dated and affect performance.
