CSS Wave Generator - Online Animated SVG & Keyframes

A CSS wave generator creates animated SVG wave patterns powered by CSS @keyframes animations. It calculates sine-wave paths for SVG <path> elements and applies continuous translateX animations, creating the illusion of flowing water or undulating waves. The generated code includes both the HTML structure (inline SVGs) and the CSS animation rules, ready to drop into any web project. Multiple layers with different amplitudes, wavelengths, colors, and speeds produce rich, organic wave effects.

Simply copy the generated HTML and CSS into your project. Place the HTML (the <div class="wave-container"> block) inside any section or container where you want the wave divider to appear. Paste the CSS (including @keyframes) into your stylesheet or a <style> tag. Make sure the parent container has position: relative and overflow: hidden for the waves to clip correctly. Adjust colors and speeds to match your design.

Absolutely. Each wave layer has independent controls for amplitude (wave height), wavelength (distance between peaks), animation speed (duration in seconds), fill color, and opacity. You can also adjust the global wave position (top or bottom divider) and background color. The live preview updates in real time, so you can fine-tune every parameter before copying the final code.

SVG-based waves offer much smoother and more realistic curves compared to CSS border-radius hacks. They support true sine-wave shapes, multiple layered waves with precise control, and perform better on most browsers since SVG path animations are GPU-accelerated. SVG waves also scale perfectly at any resolution without pixelation, making them ideal for responsive design.

Yes. The generated SVG waves are purely decorative and use aria-hidden="true" by default, so screen readers ignore them. The CSS animations use prefers-reduced-motion media query support — you can easily add a reduced-motion fallback. Since the waves are rendered as SVG within the DOM (not as background images), they don't add extra HTTP requests, which is beneficial for page load performance and Core Web Vitals scores.

Seamless looping is achieved by rendering at least 2-3 complete wave cycles within the SVG and using a translateX animation that shifts the SVG by exactly one wavelength. Since the wave pattern is periodic, when the animation resets, the visual output is identical, creating a perfect infinite loop. Our generator automatically calculates the correct SVG width and keyframe values to ensure smooth, glitch-free looping.
