Three white circles of varying sizes form a fluffy cloud. Raindrops are built with asymmetrical border‑radius to mimic a teardrop shape. The rain animation moves them downward with a rotation; two groups with a delay create a continuous downpour. All mechanics are pure CSS.

Clouds

CSS cloud shape constructed using :before and :after pseudo-elements. Linear gradients and soft shadows define depth without relying on external image assets.

Lightweight background effect implemented without external assets. Visual depth is achieved through shadow manipulation and scale transformations, ensuring high interface performance.

Pure CSS sky animation requiring no external assets. Geometric primitives form cloud shapes through pseudo-elements, while keyframes define linear motion with variable speeds.

Single-element cloud animation. Geometry defined through multiple box-shadow values. Periodic vertical translation simulates a floating effect.

Multilayered cloud animation driven by CSS background-position and keyframes. This logic-based approach creates a depth effect using stacked background layers and minimal DOM elements.

Seamless CSS cloud animation using pseudo-elements and linear gradients to define form. Motion is driven by keyframes with variable speeds and scaling, providing a depth effect entirely without external assets.

Rainy Cloud

A charming pure CSS cloud animation featuring staggered raindrops created with efficient SCSS loops. This snippet showcases the power of multiple box-shadow values to render complex shapes, keeping the HTML markup minimal and ensuring high frontend performance.

Complex CSS cloud animation built with nested geometric primitives. Visual volume is achieved by stacking varied circle sizes and radial gradient shadows. Motion logic is handled via keyframes with unique delays and speeds for a natural feel.

Easy Cloud

Minimalist CSS cloud animation constructed using pseudo-elements and border-radii. Smooth horizontal motion is implemented via transformation keyframes without external assets.

A complex animated scene built with SCSS, combining rain, lightning, and floating cloud effects. Utilizing @for loops and random() functions ensures variable particle dynamics and light flashes, resulting in an atmospheric background created entirely with pure CSS logic.

Multi-layered parallax effect powered by SCSS and repeating textures. The loop automatically generates keyframes for infinite horizontal movement at varying speeds. Clean code logic for a deep, atmospheric background experience.

The multilayered SCSS structure handles fluid, stochastic motion of background textures, delivering a deep visual impact with zero JavaScript.
