Kawaii Jelly Goo Loader
Live Preview
A delightful and squishy fluid loader designed with a 'Kawaii' aesthetic. It utilizes SVG feGaussianBlur and feColorMatrix filters to create a realistic 'gooey' effect where droplets merge seamlessly into the main body. The animation mimics a physics-based bounce with organic deformation, complemented by a blushing face and blinking eyes to maximize charm. Perfect for playful apps, children's interfaces, or creative portfolios.

Frequently Asked Questions
How does the feColorMatrix filter specifically facilitate the seamless merging of the Kawaii droplets into the main jelly body?
The gooey effect is achieved by first applying a feGaussianBlur to soften the edges of the SVG elements. The feColorMatrix then targets the alpha channel using a matrix like '1 0 0 0 0, 0 1 0 0 0, 0 0 1 0 0, 0 0 0 18 -7'. This high contrast adjustment forces the semi-transparent blurred pixels to either become fully opaque or fully transparent, creating a sharp, liquid-like bridge where the shapes overlap.
Which CSS properties are manipulated within the @keyframes to simulate the organic, non-uniform deformation of the jelly?
The deformation mimics fluid physics by animating the border-radius property across eight distinct values (e.g., 60% 40% 30% 70% / 60% 30% 70% 40%) in sync with the transform: scale() property. This multi-axis rounding change prevents the shape from looking like a perfect circle, giving it a 'squishy' aesthetic that reacts to its perceived vertical velocity.
How is the blinking eye logic synchronized with the body's movement without the use of a JavaScript timer?
The blinking effect is handled via a dedicated CSS animation that shares the same total duration as the body's bounce cycle. By using specific keyframe percentages—such as scaleY(0.1) at 48% to 52% and scaleY(1) elsewhere—the eyes are programmed to blink at the apex of the jump, creating the illusion of a reactive, living character through pure CSS timing.
In what way does the synchronized shadow element use Tailwind CSS utility classes to reinforce the perception of 3D depth?
The shadow utilizes Tailwind's 'bg-black/10' for soft transparency and is animated with an inverse scale and opacity transition. As the jelly loader's translateY value decreases (moving up), the shadow's scale() decreases and its opacity drops, providing a visual cue of increasing distance from the ground plane which is essential for the physics-based 'bounce' effect.
Can the SVG filter be modified to create a more 'viscous' or 'sticky' slime effect for a different UI theme?
Yes, the viscosity is controlled by the stdDeviation attribute in the feGaussianBlur and the alpha slope in the feColorMatrix. By increasing the stdDeviation to a higher value like 15 and decreasing the constant offset in the matrix's alpha row, the 'merging' threshold becomes wider, making the droplets appear to stretch and stick together longer before breaking apart.
