css spinner animation

30 hand-coded CSS @keyframes animations covering every production motion pattern in 2026 — loading spinners (6 variants), typewriter text effect, bouncing ball, pulse-glow buttons, morphing blobs, particle burst, ocean waves, 3D flip cards, neon flicker, skeleton loading shimmer, glitch text, solar-system orbit, liquid-fill progress, stagger list reveal, fire animation, ripple click, floating elements, infinite-scroll ticker (marquee replacement), countdown timer, path drawing, spotlight, spring bounce, confetti explosion (no canvas), breathing meditation pulse, typewriter-delete loop, aurora borealis background, card stack reveal, kinetic typography, morphing progress steps, and animated gradient mesh background. All 30 are 100% pure CSS — zero JavaScript, zero libraries, zero dependencies. GPU-accelerated via transform + opacity (compositor-thread, 60fps on mid-tier mobile, INP-friendly). Each demo uses scoped .kf-NN__* class names + prefixed @keyframes names so all 30 coexist on the same page. Respects prefers-reduced-motion. MIT-licensed.

20 hand-coded CSS loaders covering every production loading-indicator pattern developers reach for in 2026 — spinning ring loader (the canonical Material Design pattern), dot chase loader, skeleton screen loader (Facebook/LinkedIn/YouTube content-shimmer pattern), progress bar loader with shimmer, bouncing balls loader, DNA double-helix loader, glitch flicker loader, heartbeat pulse loader, circular progress with percentage, liquid fill loader, neon arc spinner, cube flip 3D loader, audio wave bars loader, morphing square loader, orbit planet loader, typing dots indicator (chat/messaging pattern), staircase step loader, infinity loop loader, gradient conic spinner (Instagram-stories pattern), and particle burst loader. All <strong>100% pure CSS</strong> — zero JavaScript, zero libraries (no react-loading-skeleton, no react-spinners, no SpinKit copy, no loading.io snippet). Every loader uses CSS <code>@keyframes</code> animation on <code>transform</code> + <code>opacity</code> only (GPU-accelerated, INP-safe — no layout thrash). Every demo includes proper <code>role="status"</code> + <code>aria-live="polite"</code> markup so screen readers announce "loading" state correctly. Every demo respects <code>prefers-reduced-motion</code>, uses scoped <code>.ld-NN__*</code> class names so multiple loaders coexist on the same page without style bleed, MIT-licensed. Drop into React, Vue, Astro, Svelte, Rails ERB, plain HTML, WordPress — zero framework dependencies.

25 hand-coded CSS spinners covering every production loading-spinner pattern developers reach for in 2026 — neon arc with glowing leading-edge dot, dual counter-rotate ring spinner, dot chase orbit (Material Design indeterminate pattern), gradient conic sweep, heartbeat pulse, audio equalizer wave bars, stacked ring helix, morphing square-to-circle, comet trail with fading tail, DNA double helix, folding cube 3D grid (SpinKit's signature pattern), ripple pulse ring (concentric circles), clock tick sweep, infinity loop stroke, bouncing elastic dots, spiral galaxy, glassmorphism loader (backdrop-filter pattern), cyberpunk segmented ring (gamer/Web3 aesthetic), breathing circle, particle scatter burst, retro TV static noise loader, liquid blob morphing, progress arc fill (determinate variant), matrix rain column (cyberpunk vertical), and aurora orb. All <strong>100% pure CSS</strong> — zero JavaScript, zero libraries (no react-spinners, no react-loading-skeleton, no SpinKit copy, no loading.io snippet). Every spinner uses CSS <code>@keyframes</code> animating <code>transform</code> + <code>opacity</code> only (GPU-accelerated, INP-safe — no layout thrash). Every demo includes proper <code>role="status"</code> + <code>aria-live="polite"</code> markup so screen readers announce loading state correctly, respects <code>prefers-reduced-motion</code>, uses scoped <code>.sp-NN__*</code> class names so multiple spinners coexist on the same page without style bleed, MIT-licensed.
